The episode starts off with Haruma prepping for his date with Ayano-san. Choco also gets ready, but Haruma says he cannot bring her. As Haruma steps out the door, he sees Makoto dashing off yelling, 'I'm late, I'm late!'

Late for what?
Meanwhile, Choco is feeling considerably down, since Haruma did not take her along.

Lover  S ~
Switch scenes back to Makoto, who's in a taxi that's stuck in traffic. She's apparently going to be very 'late for work'. (Oh, I see. Haruma's date and her 'being late for work' seems just a bit too coincidental.)
At the preview, the announcer asks top model Arisa Otokami-san to present the movie staff with bouquets. (Arisa, Ashirai…) Well, as Arisa catches a glimpse of Haruma, she winks in his direction.

Obvious plot development is obvious.
Meanwhile, Choco is sitting along at the park when Kakeru-kun comes along. He asks what's wrong, and she tells her. As he explains to her that it's normal and Haruma is just on a date, she begins to cry. Kakeru-kun becomes nervous and calls Haruma an 'awful big brother', but Choco snaps at him to never talk about Haruma that way. (Sorry Kakeru! You can't win on this one.)
At the supermarket, Chitose exhibits her consumerism.
After the movie, Haruma asks Ayano-san if she'd like to go eat. She agrees, to his delight. Chitose catches a glimpse of them as they pass her, and she is crestfallen to find Haruma with a woman. She tails them, spying on them from a restaurant across the street.
It's a small world after all. In the booth next to Chitose's, Ayano-san's ex-fiancee is talking to his former employer. He needs to leave the city to take care of a countryside inn, since his father passed away. The employer tries to (unsuccessfully) convince him to keep the job.
On coincidence, Haruma, Ayano-san, her ex-fiancee, and Chitose all leave their respective places at the same time. As such, they all end up face-to-face with each other.

Forecast calls for impending SHITSTORM
Upon seeing her ex-fiancee, Ayano-san grabs onto Haruma's arm and leads him away. After a pause, ex-fiancee and employer walk away, leaving Chitose dumbstruck. At that moment, Makoto shows up; her usual bright, cheery, and freeloader self. Chitose grabs Makoto and begins to cry.
The next morning, Haruma gets a sub-par breakfast from Choco, since she's still angry with him. Next few scenes show 3 different girls - Choco, Ayano, and Chitose - being moody.
At school, Tamami-senpai shows up. As we've learned thus far, Tamami-senpai = job offer, so I don't think I need to explain. Since Haruma's date with Ayano drained his coffers, he reluctantly accepts. Haruma calls home to let Choco know he'll return late.
Choco goes to the park to sulk, where Chitose finds her. They both decide to go eat at Chitose's place. (It seems like Choco finds Chitose to be a very motherly figure, so I'm thinking Haruma will probably end up hooking up with her.) Anyway, Choco and Chitose have a good time, eating and watching TV. It doesn't last, though, since Choco begins feeling down again. She wonders if Haruma's stopped caring about her. (Reasons cited are not taking her out as much and promising to give her a present but forgetting.)
Choco is leaving when Haruma returns.

He gives her a present to make up for the one he forgot about. (Good ol' Haruma) Chitose also gets one too, since she's always watching out for Choco. Welllllll everyone's happy again. All's well that ends well, right?

The episode opens to Tamami begging Haruma to take an emergency job position. After much nagging, he reluctantly agrees. As a good brother would, he calls Choco and tells her he'll be home late. Choco seems sad, but decides to go shopping.
On the way, she meets the two boys she played badminton with in episode 2. Apparently they're playing badminton again - and managed to get the shuttlecock stuck in a tree. Choco gets it down for them, and they leave without making sure she gets down safely. On the way down one of the branches breaks, and Choco is left hanging by one arm. Just as she is about to lose her grip, however, Sandbag comes along.

Actually, he's Kakeru-kun. Let's call him Sandbag for now.
As thanks for being her sandbag, Choco buys Sandbag an ice cream cone. Sandbag's obviously attracted to Choco, but he's a MAN so he's gotta act stand-offish. Anyway, he ends up sharing the cone with Choco…

INDIRECTU KISSU~
As Haruma walks home, he reminisces about the day's activities. Instead of being paid money, Tamami-senpai pays him in t-shirts and some movie premiere tickets. Haruma vows to never take a job from Tamami again. (Sure, okay.)
When he reaches their apartment, Choco greets him fresh from the shower.

The next day, Haruma visits a bar which he apparently vists often. It's directly across from Ayano-san's flower shop. After serving Haruma a drink, the bartender plays some really lame card trick, which results in Ayano-san entering the bar shortly after. Conversing with the bartender, Ayano mentions how she wishes she could go to the movie premiere.

Yes, that movie premiere - the one Haruma has tickets to. Haruma hastily invites her to go.
Later that day, Haruma and Choco go to the public bath because there's a hot water outage. At the bath, Choco sees Sandb- I mean, Kakeru-kun. Apparently he lives there. Choco begins changing within plain sight of Kakeru-kun, causing him a lot of mental anguish.
As Choco is about to cannonball into the bath, she's stopped by a woman already there. The woman teaches Choco all about public bathing, including the famous 'washing each other's backs' ritual. Later, she reveals her name as Midori.

On the way home, Choco says that the public bath was fun and she wants to take a bath together with Haruma. Haruma stutteringly refuses.

Looks like it's going to be an exciting episode.
Episode starts off with Choco cleaning the sink. She gets soap bubbles all over herself, and ends up washing the clothes and hanging them up to dry. While they're drying, she decides to take a nap.

Yeah uh, I'm all out of witty comments for now.
Meanwhile, Chitose is hanging out her clothes to dry. Later, as she's folding them, Choco comes and asks if she wants to go shopping together. Chitose says that she needs to fold clothes first, and Choco volunteers to help. Choco picks up one of Chitose's bras and asks her what it's used for. Despite being very embarrassed, Chitose obliges and lifts up her shirt. Well naturally Choco now wants a bra …and wants Haruma to go with her to get one, no less. Token embarrassing situation much? Haruma is opposed to the idea but eventually agrees.

Speaking of which, where ARE Haruma's parents anyway? Hmm…
Haruma is rather embarrassed to be in the lingerie shop, it couldn't get any worse unless someone he knew saw him there. Ah, too bad for Haruma… Ayano-san shows up to change the shop's floral arrangements. Despite Haruma's fears, though, Ayano seems to be rather oblivious to the implications.
Back at home, Choco immediately begins to try on her new garments. But… she has a little difficulty.

Cue for perv-Shiki?
Later that night, Chitose hears a loud thump and walks out to see Makoto lying drunk at the bottom of the steps. As Chitose tries to wake her up, Makoto suddenly begins to assault Chitose's breasts (again). With Haruma's help, Chitose manages to put drunken stupor Makoto back to bed.
The next day, Choco, Chitose, and Makoto gather for a meal. They're having a good time, and going along with the theme of the episode, their topic of conversation turns to lingerie. Choco says that she is not wearing any underwear, because she only has one pair and she wants to make it her 'game underwear'. (Game underwear is the underwear that girls wear only for the guy they like, or something…idk. It's written in her instruction manual, apparently.)

Someone really needs to confiscate that thing.
Chitose and Makoto are pretty shocked, asking her who she has in mind. Choco innocently replies, "Onii-chan."
On the way back from shopping, Choco and Chitose meet Haruma, who offers to carry Chitose's bags for her. Chitose then invites him to dinner. That night, Choco writes about how she has made her first underwear her 'game underwear', but is unsure who to have a 'game' with.
