I can totally understand him getting a mini heart attack at the end... and my for my part see the †žSee you later“ bit as confirmation of a sequel (at least in my delusion)...
Absolutely wonderful. Perfected by the "coming back home" in the letter instead of "going", making it clear that she considers his place her home now. ^_^
What a nice guy, first he grants her shelter from the rain, doesn't mind her visiting him everyday after school, and he even gave her a spare key since they get along so well. And the whole time, he didn't do anything to her. Well, that, and he didn't even ask about her situation...But at least he did in the end, which helped move things forward. But as always, the Hentai Protagonist lets slip the usual 'joke' about saying he might do something if she stays the night, and she takes him up on the offer. And hey, when they both confessed to each other during sex, it was really nice and sweet. Great ending though. Quite a nice little touch on the letter at the end where she wrote that she'll be 'coming back home', meaning that she considers his place to be her new 'home'. I really appreciate small details like this that make the reading experience that much better. Maybe one day they can become family and it'll really become her home.
