Actually in Thailand, becoming a BL/GL actor is the fastest way to get popularity and money. Just this week 2 GL screen partners becoming BAs for a high-end brand. And if it's gmmtv production, most of their released series are BLs. Anyway it's imo impossible to be completely innocent when what you chase is money. You could just enjoy the drama and stop reading about their gossips as long as they're not proven to be involved in criminal case.
I think Tay Tawan should be a good person, just insomniac. He previously has kissing scandal with Gun but I think it's normal for them? His partner Newwie should have no problem too, but he previously has girlfriend. Their most recent BL drama is Cherry Magic. But A Dog and a Plane should air soon.
Haven't watch any of currently airing Thai BL drama, but if I had to choose one maybe Me and Thee. Phuwin is a smart and hardworking cutie, he seems to have a lot of close female friends including Nanon's sister but I don't think he's dating any of them as he said he has no time to date atm. Pond was homophobic in the past but he should treat it as normal now that he's in BL industry after covid ruined his idol dream.
