I do enjoy the second couple they are sweet but the main couple truly makes this show for me. Their chemistry is insane and I love both their characters so much. Their relationship formed so naturally. There are no other BL's like this its truly so well written and thought out. The way YSG fought for HT usually never happens in BLs and it always pisses me off. Their intimate scene was so well done by the actors they truly look like their in love. My new favorite BL of all time and new favorite couple. I really don't understand people saying the second couple is better. Their story and connection isn't as intense and deep for me. But to each their own. As someone who is LGBT and in an LGBT relationship I can say that YSG and HT have a super natural and realistic relationship.
