Isshuukan Friends.

Synopsis

Kaori immediately rejects Yuki's seemingly intrusive proposal, knocking the latter into a disheartened state once more. However Yuki picks himself up with encouragement from Shogo. The next day Yuki surprises Kaori on the rooftop and explains their previous week which Kaori happily believes. The following day, Yuki suggests that Kaori keep a diary to help her remember the time they spend together and she begins documenting all the all the good and bad traits of Yuki's personality. On Friday Kaori presents Yuki with the crêpe flyer and he suggests that they visit the place on Sunday. However when they meet up, the crêperie turns out to be closed and Yuki suggests that they go to a karaoke place instead. After a fun-filled Sunday afternoon, the pair apologize to each other about their unique circumstance. That night Kaori leaves a notice for her to read the diary on Monday morning. At lunch on Monday, Kaori timidly meets with Yuki on the roof for the first time yet again and tearfully forces herself to remember him thanks to her diary. However Yuki beats himself up for her obvious pain and apologizes for his selfishness for her to remember him. However Kaori forgives him and they restart their cycle all over again.
