On the night of his college graduation, Lin Feng woke up in the hotel with a hangover. Next to him lay the iceberg goddess recognized by the whole school - his college teacher Leng Mengguan. A month later, we met by chance at the hospital. The prenatal check-up sheet she was holding clearly said "early pregnancy, twins." Faced with the unexpected arrival of two little lives, Lin Feng, who had just been abandoned by his ex, resolutely shouldered the responsibility. With the activation of the "New Dad System", he moved into the teacher's apartment, and started a ridiculous cohabitation and child-rearing life from five-star cooking skills to mysterious nutritional solutions.
