Ngl, 8+ rating for this show is kind of surprising and way too generous. Just finished it and honestly 6 is all would give it

I would say it's probably one of the best bl dramas of the year, but prepare for a lot of angst

You're in for a wild ride then

Because they do it in Thailand. Pretty much all of chinese BL dramas are made by chinese people but outside of China itself (to avoid censorship) - ABO desire for example was filmed mostly in Tawan and Hong Kong

There are exceptions (I believe Revenged Love was filmed near Shanghai), but there are nuances to that as well

I honestly dont understand why people here are bending backwards to somewhat make YSL into the toxic one. He didn't really do anything out of line at any point given the circumstances. I wonder if it's just because they want to headcanon toxic x toxic male leads or something.

Oh boy, he will suffer alright. To quote George Carlin "It's amazing what you can accomplish with a simple baseball bat" hah

Likely to signify difference in age and maturity between them. Gege is still somewhat "equal footing"

It may be just phrasing. Context is very important with certain chinese words. "Uncle/Aunt" can be used just for someone older that you respect - not strictly a family member.
