Romantic Son-In-Law

God has eyes, he was reborn as a student of Donghai University with the same name, bearing the blood debt of seven lives of Dragon Sword in his previous life, and bearing the reputation of "brother-in-law" known to the whole school in this life. A killer who repays kindness with revenge, a fiancée who thinks highly of herself... Ordinary people's lives are so colorful. Forgive me for being uninhibited, indulgent and loving freedom in this life...
