That clear a few things... but still, something like that can easily leave a mark on a relationship. Like he could easily get insecure at every time she receives a msg from now on, or go somewhere alone. Also, her thoughts and memories make me really uneasy.
Thankfully we had En-chan and Mom to lead her way. I was sure she would make a bigger mess. But damn, so unnecessary. Couldnt had been just a confession or a fail attempt of a kiss?
