Stigmata

Watch out there's a person writing spoilers for next chapter below, without any warnings >:/

I understand why seme is overthinking. We see everything from seme perspective so it's easy to sympathize with him.

In this case uke is not communicating not because he's completely unwilling (yes he is a man of few words but that's not what I'm talking about rn), but because he doesn't even know there's a problem. The uke doesn't know seme saw him with all these people... So how can he even initiate such conversation when he doesn't know what the problem is?
Seme should be the one to initiate that conversation ╮(￣▽￣)╭

Also uke clearly feels something is wrong and that is why he asked seme to walk with him home. I think he wants explanation as much as seme wants it.
