FL jealous / thinks ML lead loves someone else

I'm looking for a drama or movie where the female gets jealous or upset because she thinks ML is in love with someone else or together with someone else. Doesn't matter the county but I find it really hard to watch Chinese Dramas. 

Some examples might be:

Taiwanese movies: Love the Way You Are,  Do You Love Me As I Love You, Our Times, etc.

Japanese Drama: Konin Todoke ni Han wo Oshita, Shitter Waifu, etc.
