TAESAN LIKES KANGJUN???
thats how it appears in my opinion. since kang jun was the one who showed him kindness, taesan was able to find a safe place(?) and develop feelings for him. he also ususally blushes around kang jun and i think junwoo caught on and is blackmailing him by threatening to tell kang jun that taesan likes him. junwoo has also shown jealousy towards kang jun whenever taesan mentioned him. i could 100% be misreading it though haha.
From novel spoiler.
Not really
wait why
He is straight, and in the scene when it seems like he want to confess is actually he want to thank jun.
Welp that is what i read from the spoiler
kang jun likes junwoo, junwoo likes taesan, taesan likes kang jun, and yohan likes kang jun
