I can't remember the title of this manga and was worrying if someone could help me find it? I think it was part of a series of one/two shot chapters, and this one focused on an uke who is keeping his current lover at a distance emotionally because he's worried that he'll come off as too clingy/emotionally heavy and his lover will leave him. It's shown in a flashback that his previous lover left him because of that, since he only thought it was a casual sex thing and not an actual relationship.

I think the main clash of the chapters were that the current lover gets some call/text on his phone and goes out without telling the MC where he's going or why, and the MC ends up freaking out about the possibilities.

If anyone knows what manga I'm talking about PLEASE reply!
