Childhood Bridegroom, Where Do You Think You're Running?

A short, sweet romance [The male lead is sexually inexperienced; the female lead is physically inexperienced but foul-mouthed, so proceed with caution. The male lead has a madman streak. The plot moves quickly without dragging.] The moment he entered the Ye family, he swore he would be a good big brother. He doted on her and protected her as she grew up. But at some point, the most shameful thoughts began to stir in his heart. “You’re not my brother, and you’re not my live-in child bride either. You’re my... child bridegroom!” One sentence from the girl sent him fleeing overseas for three years. After he returned, she flirted while he dodged her. He could only watch as she found one boyfriend after another, while the darkness in his heart grew deeper and deeper. “If you can’t love me, I can give you money to leave the Ye family. From now on, we’ll be strangers in this vast world...” He gave her three parts of the aphrodisiac and took seven parts himself. “I’ve seen and tasted every part of you since we were kids...” “You said I had to stay by your side forever. Now that you’ve grown up, you don’t want me anymore?” “You’re never leaving my side in this lifetime... If you can’t love me, then hate me...” “Ranran, I never planned to be your brother.” “What a coincidence. I never thought of you as my brother either.” “With so many men, is there room for them all in your heart?” “There’s only room for you in my heart. The others are just there to keep me from getting addicted.”
