Tsukasa runs for Student Council and appoints Junichi as her vice president. However, things hit a snag when a rival candidate also names Junichi as her vice president.

Tsukasa sees Noriko about to kiss a panicked Junichi and angrily drags him to the Janitor's shed which Noriko believes her plans have work. Instead, Tsukasa kisses Junichi to calm him down, revealing she was aware it was a trick by Noriko to cause a rift between them and makes Junichi promise not to fall for Noriko's tricks or kiss any other girl than her.

Months have past since Rihoko and Junichi have taken over the Tea Club. While it's already summer classes, Kanae is still annoyed that Rihoko has yet to confess to Junichi. While both of them are cleaning the Tea Club, Junichi reveals to Rihoko that he is suffering from heat fatigue due to eating only watermelons and noodles ever since his parents went out to help his injured uncle.

Makabe decides to leave Rihoko alone after hearing who she is in love and with goes after another girl only to embarrassingly realize it's Hibiki and Haruka. Junichi returns home after Rihoko arrived to cook dinner but feels awkward around her after he secretly learns she is in love with him.

Almost a year after they started dating, Junichi and Ai are reflecting over their time together at the beach. With Junichi studying at a cram school and Ai tending to her responsibilities as captain of the swim team and at home, they are spending less time together, though they are looking forward to their date on Christmas Eve.

At the Founder's Festival, Miya and Sae's class is doing a play of Romeo and Juliet with Miya and Sae as the lead characters respectively while Ai is working at the Girl's Swim Team Oden Stand. When she gets her break time, she reflects on last year's Founder's Festival with Junichi and starts to tear up wondering how Junichi's doing.

Kaoru is doing an MC of an Inago Mask show at the amusement park getting into her role as Junichi is playing one of the evil minions. After Kaoru starts deviating from the script which sends Junichi through the stage, he retaliates by attacking Kaoru with other bad guy costumes. Flashback to before the summer break, Kaoru is helping Junichi with a art assignment and helps him, rather suggestively by sitting on the chair he's in with everyone watching.

Junichi and Kaoru are picked up by a passing truck who's driver sends them to a nearby hot spring inn with a bus stop. As they both start to argue over who's fault for missing the bus, the truck driver comments and gives some advice for the couple. Arriving at the inn, both of them realize the inn looks haunted and with only both of them the only customers, Kaoru is scared of being alone that she asks Junichi to accompany her even at the baths.

It's been about ten months since Sae and Junichi have been dating and Sae's self-confidence has broken her out of her previously shy personality thanks to Junichi. Because of this, she is able to hold conversations with others, be more efficient with her job, and be around dogs owning one herself, though big dogs still scare her.

As Tsukasa helps prepare Sae with her duties for the Founders Festival, Junichi is feeling saddened by the lack of time he is spending with Sae as well as how he doesn't know how to help Sae. While reflecting at home, Junichi reflects with several tapes of Sae in his various movies when he gets an idea to film a documentary of Sae as the head of the Founders Festival this year.

A few months have past since Haruka and Junichi have become a couple. During their date, Haruka asks Junichi when is he going to meet her parents which catches him by surprise. Haruka later reveals to Hibiki that she wants Junichi to propose to her during graduation day just like her British grandparents and her cousin, Jessica Morishima and her fiance did but doesn't want to force him.

Junichi is rather nervous of Haruka coming over as not only is she cooking for him but also staying over for the night as well which coincidentally his parents and Miya are out. As they go to bed, Haruka reveals she is leaving for England to be with her grandparents after her graduation ceremony which comes to a shock to Junichi.

In the episode, Junichi hasn't gone around with any girls yet. Miya goes to a hot spring with Sae and Ai. There she meets Tsukasa, Rihoko, Kaoru and Haruka. The main characters except Junichi enjoy girls' talk in the hot spring.
