That was a sweet chapter in its own way
You know, I was wondering. Is there ANY manga or LN which actually has a lead heroine like Rin? Aggressive, manipulative and confident-dominating, yet with a soft core? I can't think of a single one, come to think of it. And I'm not talking about a listing of tsunderes, but rather someone who matches Rin's playful-flirty type.
The only matches I can think of would be _secondary_ characters. But noone actually as the "lead" or at least "winning" girl.
Guess the japanese Market doesn't allow for that...
