Hey! I used to watch Tamil serials as a kid but they tend to go on forever so I never actually finished any of them. There was one I remember watching and I loved called Anbulla Snegithiye (Dear Friend). Its an older series and I think the ML loved/was loyal to the FL.
Some Indian movies where the ML loves the FL very much and is loyal to her (there are tons but I've just named a few here. You can completely ignore this part if you've already seen them or feel free to message me for more!) :
- Dilwale Dulhania Le Jayenge (Hindi)
- Vivah (Hindi)
- Om Shanti Om (Hindi)
- Minnale (Tamil)
- Kandukondain Kandukondain (Tamil)
- Sillunu Oru Kadhal (Tamil)
- Vaaranam Aayiram (Tamil)
- Bombay (Tamil)
Other dramas (not Indian):
Hope you find something similar to what you were looking for!
