夏海 鈴

Rin is a loner who also has a sharp tongue. At the same time, deep down she can be quite immature and just wants to be spoiled by others.

Her hobbies and special skills are studying. Her parents have high expectations of her and she gets excellent grades, but perhaps because of that, she cannot understand people who can't do the same. She refuses to listen to people who aren't either as talented as her or on good terms with her, and because of that, she has frequently gotten into trouble with teachers and other adults.

After acknowledging Haruto's credibility and upon realizing he wasn't a bad guy, she refused to be honest around him because she didn't want to look like an easy woman before yielding.
