1. Best Thai bls are-Not me,I feel you linger in the air,The Sign, moonlight chicken,my school president,dark blue kiss,love mechanics,be my favorite.
   Now some underrated ones--Why y why me(underrated),the best story(the purest),21 days theory(don't remember much),a boss and babe(nice for passing time), second chance,nitiman(I don't really remember but maybe I enjoyed it),my ride(good for one time watch),fish upon the sky(2nd couple is my life),night dream(the chemistry is sizzling,the plot not so much,a quick watch),to be continued(this just ended,but it's really too cute,the plot is medicore)You are my sky(it"s a crime how underrated this is),our days(my introvert couple),I will knock you(it gave me some kinda peace,I don't recommend to watch it but maybe I do),love in translation(crowned for chemistry and acting skills let down by plot but still great,the shorter guy was in our days,he rocked there),only boo(super cute, highly recommended)
   
   These are not in exact order and neither I am saying all of these are perfect,but I liked them to some extent,mostly the underrated ones,they kinda clicked,either with their acting skills or their chemistry,in Thai bls plot hardly ever clicks with me.

2.Best Koren bls-Eighth sense,our dating sim,to my star 1&2,where your eyes linger,you make me dance,a shoulder to cry one,long time no see and all of the strongberry bls,love for love's sake,a shoulder to cry on(my comfort drama),starstruck,an unintentional love story,a breeze of love or weather forecast love,first love again,behind the shadow(if you don't watch this one you are not real bl fan),love class2(it's criminally underrated),sing my crush(cute),the new employee(so good),the director who buys me dinner,once again,color rush.the lover,life is beautiful(bl part is good)

Jazz for two was visually good,

These are not in exact order either,but I liked them nevertheless, except starstruck and in some sense the director who buys me dinner all are good,these two,I don't know why I liked them.
