I quite liked this season. To be frank, I don't remember too much about season 1, so I don't have much comparison. I do remember the actors, though, so it was great to see them cameo in the middle of the season! I also like that there were three couples and each couple had their own issues to work out (though one couple I seriously could have done w/o).
I think the main couple had a lot of challenges with trust and vulnerability which is why KA didn't talk about his past and LH didn't push about it. Seeing KA's past, it makes sense. He's deeply traumatized, so any form of intimacy makes him scared because he doesn't know what's coming next. Will they leave? Will they betray him? It's hard for him to feel like he can have friends/chosen family or romantic relationships. From there, I like that there was a natural progress of them building trust by relying on each other and demonstrating that they can be trusted with difficult topics. I really appreciated that the whole Love Class/marriage and family theme talked about building relationships in an actually healthy way - there's a lot of build-up to a quality relationship - and that that genuinely helped them to grow together as a couple. I must say, as usual, I am disappointed by the poor kissing by the main couple but...I'm not surprised since LH is an idol IRL. They always let them star in BLs but they don't let them actually make it feel like a true BL. I suppose, at least it wasn't an angle kiss.
The second couple - MR and MW - were a bit confusing at first. Right away I understood MW liked MR, but it wasn't clear whether MR was being dense or genuinely didn't know that his best friend liked him. I didn't really enjoy the manipulation tactics with the faking having a girlfriend in order to get your crush to date you. However, it does force people to face their feelings, MR in this case; in the end, it worked out and they didn't have hard feelings. I must add, too, MR stole the show. His personality and silly antics were super entertaining and precious. I'm w MW on this one - he's too cute not to date lol Also, A- for the kissing. It definitely got better over time but the beginning with non-con kissing...Big question. MR was awake but MW didn't get consent so \o.o/ no bueno.
The third couple - JK and SM - were just...awful, to be honest. I didn't appreciate their dynamic at all, and they were toxic asf. Between the childish "playing hard to get" to the misunderstandings about JK's relationship with his uncle (??? tf, so underdeveloped and confusing), all of it was deeply unimpressive and their relationship didn't make sense to me. I mean, the end revealed that SM knew JK before he left for the army and came back, so did he have feelings then and he developed them now? Idk. Also, let's talk about that weird underwear gift...That whole scene made me cringe big time. Then to threaten him and the whole thing - so fucking unnecessary. A for actually kissing though. The "bed scene" (NC-17 at best, but read a bit PG-13) was decent though it didn't go beyond making out. I guess that's a start considering KBL at the beginning could barely even fit in a kiss lol
Overall, I enjoyed it even though some of the mistakes were a bit bummy. The whole thing with the boom mic really wasn't notable. I only noticed it in one episode a couple of times, but I don't remember it anywhere else. The audio in general could have been a bit better, too.
