The two main leads have a lot of complexity written into their characters and they portray mixed emotions very well. My take on the drama;

I see Mark as a person who knows he can love wholeheartedly and when he is disappointed in not winning his intended love interest he backs off and tries to deal with the aftermath of feelings by drinking and looking for random hook-ups. The scene of drunken mistaken identity is more a fanciful wish on his part and gives Mark the chance to act out the passionate love scene he has missed out on.

Vee is in a long term committed relationship with his girlfriend and has a strong need to be helpful and have others like him. He assists the very inebriated Mark and when Mark throws himself at him he finds himself turned on and reciprocates. This sexual encounter affects both of them badly. Mark is angry and hates Vee for the encounter. Vee is confused and begins to realise he is sexually attracted to Mark and then the story unfolds.

Youth in university exploring their sexuality without yet fully understanding what is required to maintain a relationship. Friends adding their own input to the confusion. Jelousy, judgements, sacrifice and selfishness overlaid with raging hormones and insecurities.

The parents add some interesting dynamics to the mix and the two male leads are influenced by their attitudes.

As a love story it has fulfilled this role. The two MLs have a strong chemistry and they are sufficiently different to add the angsty thought that maybe they won't be able to stay together.
Very watchable and rewatchable.
