Jun'ichi is in hot water after inviting Minato to watch a movie with him, and neglecting to to invite Yuuhi, so Minato fakes a phone call, forcing Jun'ichi and Yuuhi into a date. The next day, the date is the talk of the school.

Jun'ichi and his friends visit a mountain resort, and Karen takes the group on a long hike to the Ayanokouji family's secret hot spring?which they soon find out is a co-ed bath.

It's the school Cultural Festival and Yuuhi, Karen, Fuyuhiko and Tsukasa (along with the rest of their classmates) are doing a Yakisoba café. However, they face tough competition from the Yakisoba stand put up by Minato and the tennis club.

Minato convinces Yuuhi to help with Jun'ich's surprise birthday party by getting Jun'ichi's present, but Yuuhi has a difficult time choosing a gift. Minato offers to let Yuuhi bake the cake instead as her present to Jun'ichi.

Yuuhi fakes being sick so Jun'ichi will stay home from school to care for her. That's when she demands a redo first kiss. Everything seems ready to fall into place, until Minato takes the chance to drop a bombshell announcement.

Yuuhi meets with her father and rejects her engagement to Jun'ichi, saying she'd rather decide for herself without external pressures. Upon her return Yuuhi senses some weirdness she can't place in the Nagase home, but neither Minato nor Jun'ichi are willing to admit anything.

After Jun'ichi came back home after meeting his parents, Yuuhi was so angry over Jun'ichi lying to her that she decided to break up with him and leave the house that night. The next day, Minato left the house as well in order for Jun'ichi to make a decision between her and Yuuhi.

For summer break, Jun'ichi and the group head to one of Ayanokouji's family's privately owned islands. But, the school president has a secret plan to make this vacation as, um, interesting as possible.
