My Childhood Friend Omega Brother Is an Alpha?!

[Dual Male Leads + ABO + Mutual Firsts + 1v1 + Childhood Friends + Reunion + Sweet Romance + Alpha Pretending to Be an Omega]

Yan Yuan has just been dumped. His buddies take him to a bar to cheer him up, where he runs into his neighbor's omega little brother, who has inexplicably been drugged by a friend.

The omega has just returned from abroad and is having trouble adjusting to life back home. Yan Yuan takes responsibility for looking after him, offering advice and comfort, helping him find a place to live, and treating him to delicious food. Eventually, he even moves in with him to keep him safe. But...

Yan Yuan, puzzled: “Yanyan, have you gotten taller again?”

Wen Anyan, aggrieved: “Wah, does Big Brother think I'm too tall, not as petite and cute as other omegas?”

Yan Yuan, waving his hands frantically: “No, no. You're cute no matter how tall you get.”

Wen Anyan lowers his head with a little sob, then awkwardly leans against his big brother, his lips lightly pressed to the back of his neck, his eyes full of possessiveness and frenzied love.

As long as Big Brother doesn't find out I'm an alpha, I can be his omega for the rest of my life...
