Good news! So far (ep. 12), there is none of the other triggers besides the suicide which happens in the 1st part of the first episode! (also, some unsupportive family of the past couple, which leads to the suicide). Other then that it is very cute, soft and fluffy with everything consentual and when one of the leads is uncomfortable with what is happening, they voice it out and they talk it out together. It is honestly the cutest thai bl drama i've seen and i dont believe there is a chance the vibe might change drastically in the following episodes (though i did not read the novel... you never know with thai bls)
Unfortunately, i dont know any site where you could find these possible triggers. Here on MDL, each drama has a tag section - you can open the full tags by clicking "Vote or add tags" to see all of the tags, including spoilers and possible triggers (if someone tagged it). however, i checked some dramas and seems like people are not always tagging all the stuff.
I recommend asking here on forums or at the drama page (preferrably - higher chance more people will answer you) and i'm sure people will help you. If you have any questions about about dramas i've seen, i'll gladly help you, too :) (if i remember, haha...).
I dont mean to generalize, but with thai dramas (or.. BLs, cause that is what i watch) it is always better to ask beforehand someone else if there are any triggerring elements because they use them a lot ://
