Firstly the stories are different.
In 2gether, a case of unrequited love with an uke that is unwilling and mostly scared to explore that part of a homosexual relationship with his partner. Sarawat had a completely different approach in seducing win/tine and having a relationship with him. Which admittedly isn't really sexual. Plus the actors had a different vibe
In bad buddy. Ohm whom has had experience playing a dominant role in several bls. Is confident and sexually mature enough to put an obvious sexual undertone to the series. Even though they are playing the series as two friends. There is a secret intimacy there.
So while 2gether is tame in terms of sexual chemistry. I believe the actors had good rapport and made a very attractive couple.
While for ohmnannon err patpran they fought against an obvious sexual attraction that manifests in a giddy sort of sexual chemistry. Like there's an undercurrent, you keep anticipating them to do something naughty at any moment
Anyways.
