- Description from novelbuddy

After transmigrating, Liu Changqing skipped over the dating phase and was thrust straight into fatherhood with a son and a daughter. This left him in a gloomy state. His eldest son is mature and intelligent, while his young daughter, resentful of her parents’ divorce, blames Liu Changqing for everything and treats him with hostility.The original owner of this body was the ultimate “simp.” He grovelled so much that his ex-mother-in-law’s single agreement allowed his ex-wife to take away all the family assets in exchange for custody of their two children.Now, with his factory bankrupt, Liu Changqing is racking his brain over how to raise his son and daughter. This has become his biggest headache.——————————————No reconciliation, no groveling, and firmly grounded values.
