These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Funny Moment: During Masahiko's 19th birthday, he and Asaoka ran from the party to his room not to see transgendered individuals dancing around naked, he decides to start opening presents because the atmosphere was getting too intimate. The first one he opens contains three packs of condoms with a note "Make good use of these with Asaoka". He promptly hides them so she doesn't see what it really is.
Heartwarming Moments: Several, including when Sora first proposed to Yukari on their shared 19th birthday.
