Name a drama/movie with this theme

[aznchic209]

Please name some dramas or movies with a theme like this:

1) A friend falls for someone but asks their friends not to fall for that same person. He/she dies and later on, one of the friends ends up falling for that same person and feels extremely guilty

2) Two people fall in love but something happens and one of them dies. Years later, one person meets someone that looks just like their dead gf/bf and falls in love with that person

It doesn't have to be exactly like this but similar to this. It could be falling for the relative of the deceased, a sibling, a twin or a friend and it doesn't have to be Asian dramas/movies only. It could be anything with these themes.

Here's some that I've already seen or am watching with that theme:

- Which Planet From Are From (Korean)

- After School Bolbulbok (Korean)

- Shut Up Flower Boy Band (Korean)

- Summer Fever (Taiwanese)

- Catch & Release (American movie)

- Sud Sai Pan (Thai)

- Ngao Jai (Thai)

- Persevere Goo Hae Ra (Korean)

- Someone Like You (Taiwanese)
