ML Falls For FL Quickly? BL Welcome!

Any romance dramas or mini dramas where the male lead falls for the female lead quickly, before ep 5. It can be from China, Thailand, South Korea, or Taiwan. BL is also welcome! When I mean "fall", I mean it has to be clear to the viewers that the male lead is starting to like the female lead or looks at her in a different way. 

Also, no need to check my watchlist ^^

 Lou:

Kinda not really such a fan of BL so these are all recs without bl.

Korean;
Something in the Rain
One Spring Night
Whats wrong with secretary Kim
When Camellia blooms

Taiwan;
Hello Again
Someday or One Day (this is a tricky one, but might be also something)
Triad Princess
Before we get married

China:
My Little Happiness
Go Go Squid 2 
Find Yourself

Thailand:
Game of Outlaws (the romance is not the main plot but its the only thai drama i can think of where the romance between the lead is there from the beginning to the end)

Thankyou so much!! ^^
