I like how the sunbae is observant and already understands the type of personality the other has. I'm also glad he didn't confess too ngl that would've ended up with more drama n stuff
i think hes distancing because of that flashback past trauma. hes become afraid of being the cause of someone's pain. he is not distancing because hes aware he likes sunbae,if thats the case, he wouldve distanced himself from the first couple.
if someone/something c*ckblocks them I WILL LOSE IT!!
