For starters, this series is a spin off of the patent story 'En of Love' so it doesn't matter which one you watch first but personally I'd watch EOL so you get a general idea of YinWar. They're probably my fav current BL couple but unfortunately, this series didn't change much of how they were in EOL.
ANYWAY, if I'm not comparing it then I really enjoyed this series. It has its basic Thai BL cringe and cute moments but YinWar is pretty much a dynamic duo you can't help but can scream for lol We can all realize to the characters in some way, whether it's school stress, family troubles, being cheated on etc everyone has a story here. I feel the end got rushed a LOT and it definitely had its good, bad and ugly moments but if you're looking for a cute MC with decent romance and fluffy BL cuteness and drama...look no further
Enjoy....
P.S. last ep after credits had me SCREAMING
