Yan Chengxi just went to a private clinic to have his teeth extracted, so why did he meet the legendary childhood sweetheart he hadn't seen for many years? What's even worse is that the big devil Gu Yibei is the top dentist in city A introduced by his aunt! Pooh! All of his baby teeth were knocked out by this bastard, and now he actually asked him to treat his teeth? "Gu, don't break the law! Do you understand that this is forced consumption?" "Be good, I won't charge you." "Get out!!" This is a story about a tsundere and a gentle and domineering attack. It's a sadistic story. Welcome to join in the trap~~
