Heyy

Help, so im looking for this bl manhwa that suddenly popped into my head, I only remember 1 scene where the mc or ml was not answering their phone and the orher one was panicking asf and he found him in a train station with all his stuff and turns out that whenever he feels like sad or sum he always packs his stuff and sits at the train station the monologue goes like this (I almost lost you a lot of times). I think my explanation sucks but thats all I could remember
