Number one hero Izuku Midoriya, and number two hero Katsuki Bakugo. They're so, painfully obviously in LOVE with each other. Having been trough all couple troupes in existence, childhood friends, enemies to lovers (except they're not lovers yet), grumpy x sunshine, sun and moon, mutual pining, everyone notices but them, ETC. And now, they're experiencing co-parenting. Fate can really be interesting sometimes.
