Lf bl manga

manga where the mc is a somewhat successful businessman of sorts who gets kidnapped. his kidnapper turned out to be a victim of child kidnapping that the mc had an (unintentional) hand in as a child himself. i remember at some point it shows the ml holding the hand of his kidnapper and he talks about how in a way he also loved him. they both come to understand each other other somehow and end up growing old together. iirc they’re fishing together as old men
