the sad part is, that its the most realistic ending. They are all gonna date other people and fuck them while the main MC stays alone for life LOL worst fucking manga ever, DO NOT READ STAY AWAY
To the people saying this manga was crap...
I understand you hate the way it ended, I do too. But let's not blow it out of proportion just because you didn't like the ending.
If you really thought it was crap you wouldn't have read this far.
