FL goes back to Ex. Ex is the ML

any drama where ex couples get back together? like go back couple or emergency couple. 

preferably non korean. because ive seen many of this genre from Skorea. but i wanna see others too like from japan china etc

Proong Nee Gor Ruk Ter they break up for very reasonable reasons and up to the end I wondered how they could get back together

Summer's Desire both MLs are her exes. This is old but I still love it. theres also a lesser, recent remake Summer's Desire 

We Best Love: Fighting Mr. 2nd this is the second part of a two part BL webseries. It is quite good. They get together in the first part We Best Love: No. 1 For You

My Sunshine 

The Devil Punisher Fantasy drama in modern setting, like Goblin.
