Essence of Gacha in Marvel

A boy suddenly finds himself in a world similar yet so different from his, with the essence of gacha in his pocket. ---------- Tired of waiting for the OG, so decided to make one myself. Heavily inspired from the OG, though this won't be a copy of that. And for non-harem fans, sorry bros I'll have to disappoint you. After all, why settle for one, when there are many?
