I will say low tide in twilight/waterside for me cuz at first the omega has trauma and it might be all depression but the alpha most of the times can be silly and all he wants is "sex" and the omega always kicks him or punch him everywhere his lips,his teeth,his stomach,his leg even in his balls but I swear the side stories are WAYYY sillier and better. Trust me twin you will like it (=・ω・=)
ive read it a lot, but i can agree it was a rly cute one
Maybe try this
