As I said in the cover of this review, this is a great example of how multiple couple story in BL series is done. Not messy, clear story, interconnected to each one of the couple and most important is it make sense.
I've seen multiple BL that tried to incorporate not just 1, 2, 3 but 4 couple in one series and it's a hell of a mess! It's not connected to each other, and if it is, it does not make any sense to the story. I am not shaming any country on this review but Thailand BL does this a lot and more often than not, it's more confusing and leaves the viewers on WHAT!!? WHY!!?? HOW!!??

Love Class 2 is the first Korean BL that introduces multiple couple and they did a great job!
The teacher-student fiasco is such a cute one especially the progression of their story. KIm An and Joo Hyuk is perfect and they did a great job! Their kissing and bed scenes and tastefully done, in fact all three couple's romantic scenes are tastefully done. It's not sexual in a sense that you would imagine it's a gay porn, it's not!
Bestfriend to lovers has always a place in my heart. Ma Roo's sweet face and charisma and Min Woo's child-like but super protective traits is one too watch! This couple sue nailed their role!
The third couple on the other hand is somewhat "fine" to me. Senior and junior to lovers, I feel like this two needs a bit of sugar or maybe the chemistry.....Other than that they did a great job in acting.
If i were to rate each couple it would be.... 1 - Teacher and Student, 2- Bestfriends and last would be the Senior and Junior.

WITH ALL THIS THOUGHTS, I HIGHLY RECOMMEND WATCHING THIS FRESH BL SERIES. IT'S FLUFFY, LIGHT AND CUTE. LESS DRAMA, MORE CUTENESS!
