Round One

Both are gmmtv produced thai boys love shows. One character standing in the limelight, the other on the sides observing. Share the same director too.
Round One will probably get a banger soundtrack too, as Gawin has sung a lot of OSTs in the past and will probably record some songs for this too.

Both are gmmtv produced thai boys love dramas.
Both feature the same pairing - JossGawin.
Both seem to contain some more risky/nc scenes.

Gmmtv produced BL dramas with a main character that is a boxer who becomes involved with somebody of a different (but adjacent or connected) profession (Wandee is a doctor of some sorts treating Yoryak, Nick is a journalist writing about Zack in Round One) through a fateful encounter. I dont think that aesthetically theyre too different either. Seems like round One will also include some nc scenes.

GMMTV produced Boys Love shows that have some kind of time manipulation element and that star (Fluke) Gawin Caskey in on of the main roles.

Both are thai boys love shows with the main characters finding themselves stuck in a time loop. Subsequently, they try to escape or break it while falling in love on the way.
