SOTUS (2016)

Oxygen is similar to Sotus because they are both college aged Boys Love series. Gui and Solo are a lot like Arthit and Kongpob, but very much have their own story. Konpob and Arthit will make and break your heart just as much as GuiSolo.

Both are really sweet Bl storys where one guy is insecure but the other guy makes him see that their love isn't wrong.

Both of them are BL
Acting is good
Has a good storyline
Available in youtube
and english subtitle is also available

Both dramas takes place in campus setting. The male leads in both drama also have initial animosity but later on develops feelings for each other. One of the male leads in both drama are in Engineering department of the university.

An interesting and warm relationship between two young men.
Good chemistry and acting
Good storyline.

It has the same enemies to lover trope, as long as the same concept of how one person "bets" that they'd make the other fall for them. It also has the similar shy but sharp tongued uke and the flirty but gentlemen like seme who tease the uke to no end

The main leads banter with each other in the whole series in a similar way.
Rak Diao or One love is an amazing sitcom with love hate relationship
