>>61109285That manga is about a dude who was accidentally set to have 100 soulmates instead of 1 by the god of love and is determined to date them all and make them happy since they'll die otherwise. Anytime he meets a new soulmate it's represented by that zing effect because it's love at first sight. It's pretty good and it's nice that the MC isn't a little bitch like most romcom/harem MCs
