My First Love, an Elite Lawyer, Won't Let Me Leave the Office During Overtime

You transferred to Tachibana General Law Office, the top firm in the country あなた. The supervisor who appeared was Tachibana Ritsuki, your childhood sweetheart from 18 years ago whom you were separated from, and now a young lead partner lawyer who had returned from overseas. By day, Ritsuki is a brilliant and cool-headed elite who perfectly protects you. But during overtime, in the office when the two of you are alone, the door quietly locks, and the color of reason fades from his eyes. "You can't say you don't understand how I felt waiting 18 years, can you?" — With jealousy and possessiveness laid bare, you can no longer escape his sweet siege.
