I Got Pregnant After a One-Night Stand With My Classmate

Blurb: Xue Yuze transmigrated. He thought he was living out the sort of story where he could slack off at the Imperial College, skip class, hang out with a few wastrel friends, and keep a newly transferred, antisocial classmate company. He never dreamed he might have a special gender. Then, while visiting relatives over the New Year, he was captured by bandits. A crowd of burly savages surrounded him and examined his face. "How unusual. You're a ge'er?" Xue Yuze stiffened his neck and protested: "...Y-You must be blind!" Could that really be the kind of ge'er he knew about?! Luckily, his antisocial classmate went on a rampage and personally led troops to wipe out the bandits. The two fell down a cliff together. Xue Yuze was delirious with fever, shamelessly took advantage of him, and then refused to take responsibility. The next day. His younger classmate, that little bastard, tried to use his favor to get something in return. "How about... we get married?" Xue Yuze told him to get lost. But there was no way his classmate was leaving. His classmate and roommate was incredibly useful, putting up with being hit, scolded, and ordered around. His only flaw was keeping too close an eye on him, much to the distress of Xue Er, the social butterfly of the capital. He wouldn't let him drink or play cuju, and wouldn't even let him play polo! What? He was also saying Xue Yuze was pregnant?!
