"Close Friend Season 3: Soju Bomb" and "Love Is Like a Cat" (with Mew Suppasit) are a study in contrasts in how to do, and not do, Thai-Korean collaborations.
Both are lightweight comedies. "Soju Bomb" (final episode tomorrow) is a zany comedy, and it's unclear to what extent it will become a BL. As to the Thai-Korean collaboration, the writer seems to have put some effort into a story in which there's a real purpose to these five very cute boys being in Korea. The young actors have also put some obvious effort into learning Korean lines (or maybe they knew some Korean already, but I doubt it). The language barrier is handled quite naturally.
"Love Is Like a Cat" (now through Episode 6 of 12) will presumably be a straightforward BL rom-com. There are some good things about it - but in terms of the Thai-Korean collaboration, it's very lazy. There seems to be no interesting purpose for Mew to be there, other than to appeal to his fans in KBL fandom. Mew supposedly understands Korean perfectly but says answers virtually everything in Thai - and the way the language barrier is handled is so annoying articial. I don't feel much effort.
I'm not necessarily un-recommending "Love Is Like a Cat", but I sure hope this is not the future of Thai-Korean collaborations. My hopes for "Wuju Bakery" are still high.
P.S. "Soju Bomb" is a stand-alone series and actually has nothing to do with Seasons 1 and 2.
