The Straight Guy Must Be Bent Starting in Kindergarten [Reborn]

The day he is reborn, Rui Xingxing is lying on a kindergarten bed when he hears a clear, piercing cry beside him. He turns and sees a fair, rosy face. It looks familiar. Oh, it's the eldest son of the Qi family, who acquires his family's business twenty-five years from now. Rui Xingxing and Qi Chang are neighbors. He doesn't like this pretty little crybaby. If their villas weren't next door to each other, he would never have gotten to know such a sissy... if only he'd known this sissy would grow to be six foot three twenty years later. The crying beside him grows louder. Rui Xingxing turns his head. "Stop crying." Annoying. Qi Chang hiccups through his tears. Rui Xingxing: ... "Come here. I'll sleep with you." Qi Chang's eyes light up, and he immediately takes his little legs over the bed rail and crawls into Rui Xingxing's blanket. Rui Xingxing stares at the ceiling. If he starts raising a kid now, maybe his family's company won't go bankrupt twenty years from now... Huh? Why's it wet... Rui Xingxing lifts the blanket, and his eyes go dark. "Qi Chang, you're five and you still wet the bed!?" Qi Chang's peach-blossom eyes are crystal clear. "Teacher says animals mark their things like this."
