Isn't He Supposed to Be My Chaste Archrival? So Why Does He Keep Trying to Steal Kisses?

[A 3S-class alpha who seems cold, chaste, and unapproachable, but privately is clingy and all talk, always cuddling up to his wife x A seemingly spoiled and willful young master who is actually a warm, optimistic ray of sunshine; an ABO recipient of ambiguous gender]

Lan Xi has amnesia, though only about 30% of his memories are gone.

His life has gone back from age twenty-five to nineteen. His home is gone, his dad has emigrated, he’s forgotten where he put his ID, and he has amnesia. To top it off, his nemesis insists that he’s in love with him.

From the start, everything has gone spectacularly wrong. With nowhere else to go, he can only move in with his nemesis.

Not long after they start living together, Lan Xi hides under the covers, biting his finger as he posts for help:

“What should I do after a strong alpha kissed my neck and sent my heart racing like crazy? Note: I’m the strongest alpha on earth, and I’m attracted to omegas.”

“My nemesis insists I’m in love with him. I said I’d move out, and he sneaked a kiss onto my hand in the middle of the night. What do I do? Note: I’m hiding under the covers, trembling and too scared to make a sound. I need an answer, ASAP!”

“My nemesis acts like a perfect gentleman outside, all cold, chaste, and unapproachable, but at home he’s hopelessly obsessed with me. Yet he insists I’m the one who likes him. Is that an emotional disorder? Note: Watching my nemesis go crazy over me feels so good~ Hehe~”

“My strong alpha nemesis is in his rut and wants my pheromones to calm him down, but I can’t release anything at all! Help!!! Note: I have a fully developed, healthy gland!”

Later...

Someone saw the head of the Fu family, who was rumored to have difficulty with close contact, clutching the fallen beauty who had hit rock bottom and kissing him desperately.

“I’m the one begging for your love. I’m the one who loves you. I’m the one who loves you but can’t have you, with a desire that will never be sated.”
