I vaguely remember what happened in this manga because I read it years ago.... and I only remember reading the 1st chapter because it hasn't updated yet.

What happened was this girl was caught by the main lead's (boy) friends and was locked in this classroom with the main guy. He ended up pushing her down but she managed to escape. The guy's friends asked him if they should chas her but he says just to let her go.... and said something along the lines of he'll do something about it later?

I'm so sorry I can't provide much information (and I'm honestly not too sure if what I provided is even accurate) but if you guys have anything in mind that fits or slightly fits the description please do tell me ^^ thank you~
