sooo he never talks about it with jaehyun because not talking about problems has always been their Thing and a lot of things have changed for the better but they're still not perfect. taesan thinks jaehyun doesn't remember and it's too late now, that it might ruin the peace that jaehyun has created with riwoo and he also doesn't want to rip that wound open for himself again. jaehyun Does in fact remember and he already talked about it with riwoo because communication is a very important part of their relationship (something he could never get quite right with taesan). but i do think taesan talks about it with sungho and it helps sungho understand a bit better everything that taesan did because yeah that's kinda fucked up. and also one of the conditions of them getting back together and moving in together is sungho wanting taesan to go to therapy YAYYY so he works through it. um anyway sorry for the long ass answer i think about it a lot 🥹
