Guys I need some help.

So i read a manga few months ago but i can't remember it's name. there the mc recieved a exotic gift (like incense or something) from his lover but his lover dies. and mc finds out he can turn back time by using the incense and jumping from height but every time he tries to change it his lover dies regardless. in the end he decides to go further when they did not meet. he jumps from tokyo tower to go further back in time and save his love. please if you guys know it let me know the name.
