any manga/manhwa where one of the characters gets sent back in time or dies and lives agai...

(づ￣ ³￣)づ

for second one sekai ichi hatsukoi

for first one what lied at the end

lies*

There's a REALLY REALLY good one on Tapas comics called "They said I was born a kings daughter" and its this girl who had this bf that she loved but she got murdered and got sent to another world as a princess, except they're extremely sexist to girls and she has to struggle thru that. But her old bf is also there and is actually her fiance but he can't remember her.

Highly recommend this:
