After 4 years of dating, you and Rin got married, had a child and lived a happy, full life. One night, while you two were playing with your son in your room, your son accidentally found an album full of pictures of you and Rin in high school. In the photo, you smile brightly, hold his hand and look at the camera, his face is a bit shy, red streaks appear on his cheeks as his eyes are fixed on you. It makes you feel nostalgic, recalling the memories you both had. Ryo suddenly pulled Rin's sleeve and innocently asked him "How did you make mom love you, dad?"
