But they recently started having sex in addition to other comforting methods... I loved Ryu 10000 times more after reading chapter 4, he's so dramatic and funny. Adorable
Usagi no Mori
While its a trope I usually don't like very much, the mangaka takes her time with it and its lovely.

Because you can't deepen your relationship if you hide the truth from each other
