Consensual LGBTQ Relationships

(Also true for its sequel Last Twilight in Phuket.  I haven't seen the second sequel yet so I can't comment on that.)

Unclear whether it's a main relationship, but there is a surprise kiss.  The relationship with the most screentime, however, is fully consensual with no surprises.

It's all consensual; however, one scene is shot to heavily imply one ML is going to SA the other, and the episode ends on a cliffhanger making the viewer think it's going to happen. In the next episode, the ML in question clarifies that he only has sex when both parties are in their rational minds, and that he didn't touch the other ML. But please be aware of that scene if you're sensitive to SA.

The FL is functionally a trans woman in a straight romance.

Except that the first kiss happens when one kisses the other while he's asleep.

Caveat: Before they get together, one ML kisses the other on the cheek while the other is asleep.

Adding for the secondary gay couple (one does punch the other in a mistaken attempt to defend his sister's honor, though)

As consensual as a relationship can be when one has a hidden identity.

The main couple is all consensual, but one of the MLs is shown in a relationship with someone (before the two get together) who pushes his sexual boundaries. Also, the second couple involves blackmail.

The main couple is all consensual, but one of the MLs does get sexually harassed by the SML.

Trans woman and straight cis man

(Note: There's a surprise kiss in here that a friend considers noncon, but the surprised party would have consented if asked, so I consider it consensual.)
