There’s a specific reincarnation story I’ve been meaning to find. It’s about this war god dude who has to go through several reincarnations for some kind of trial he must overcome and the goddess whose in love with him secretly joins him every time he reincarnates. In one of their reincarnations they gender swapped and their childhood girl friend accidentally killed them both by knocking one of them into an incoming train iirc

iirc it’s a spin off series. a boy whose from a temple/shrine and a young master type who creates curses and has a shitty personality. his brother is his servant and also is into the brother (lol). i think the boy who comes from the temple/shrine has messed up memories, the young master and the temple boy bicker a lot but still have feelings for each other.
