Interstellar: The Colonel's Fear of Marriage

When he woke up, Lin Chengxi was shocked to discover that he had somehow arrived in another world! As an ambitious alpha, Lin Chengxi had just decided to devote his life to serving the Empire and making his mark when he ran into his husband from his previous life. And his husband now seemed to be a poor little thing! And... it seemed he had accidentally gotten him pregnant. Lin Chengxi: ???(?°?°?) The Crown Prince (shy and expectant): When are you going to marry me? Lin Chengxi: N-no... no... (He stutters whenever he gets nervous.) The Crown Prince: You don't know? Lin Chengxi: I'm not marrying you... The Crown Prince (in disbelief): Sob, sob... Lin Chengxi: What am I supposed to do about my fear of marriage? Also... isn't your whole vibe wrong!!!! A cold, frigid, seemingly aloof (but not really) top with a fear of marriage, and a sweet, affectionate, enthusiastic bottom who's completely lovestruck. Note: Updates every other day, at 1 a.m. In their previous life, the top was the bottom's Crown Princess. In this life, he becomes the bottom's husband. The bottom regains his memories from his previous life partway through, then discovers he has a baby. A sweet, fluffy, brainless romance, mainly about dating. One-on-one, very sweet. Early on, the story is mostly from the bottom's perspective; later, it's mostly from the top's.
