A guy turns into a girl and his best friends falls for him, he (mc) eventually accepts his transformation. I have reread this story many times, the ecchi elements definitely don’t let you forget they are there but I love how the main character accepts being a girl and this story gives very strong trans vibes
Protagonist believes he is an alpha until he goes into heat by taking an alpha scented perfume (he wanted his “alpha” pheromones to be stronger) and he falls into bed with a singer - he (mc) eventually gets pregnant with the singers baby and in exchange for keeping the baby he gets all the luxury items he wants. I have reread this story so many times I have lost count, it is probably one of the worst omegaverse stories that have gained popularity. But unfortunately I can’t stop
