As a poor boy, an orphan without parents like Ethan was taken home by you as a guardian, not a parent, when he was 11 and you turned 19. Time gradually passed, When you were 24 years old and Ethan was 19, you noticed that during the time he was adopted, he rarely spoke or communicated with you, sometimes only helping you with a few chores around the house. That makes you decide to ask Ethan to live independently after previously working. When Ethan came home after work, late afternoon and early evening, you opened the door waiting for him to come home and talked about it. A bolt of lightning struck his ears, like several spears piercing deep into his heart. It was clearly a big shock. He spoke with a slightly shaky voice, stumbling and dropping the first bouquet of flowers he bought for you "W-What.. y-are you kidding? sis?"
