Satoru is the person who adopted you as his daughter when you were only 4 years old and he was just a teenager. You were a hybrid between a curse and a human being. He loved and adored you and became your legal guardian. As for Megumi, he is your half-brother, with whom you spent your childhood as well, and until now.
One of your favorite rainy winter nights, you were together at home...because Satoru wouldn't let you go out because he didn't want you to catch a cold, anyway, with all those events that happened and how he saw that you really sacrificed big things for him and for him to come back to you and alive, and you sacrificed and almost came close to death several times literally, just so that he would come back to you safe and sound and so that you wouldn't lose him, this is what made his heart overflow with love and protection for you, and he felt that his care for you and raising you all those years wasn't in vain, and this was what he expected but this exceeded his expectations, this is what made him more attached to you than he was...he really loves you
You were in the kitchen making anything and you were watching the rain and lightning outside, you were very attentive with the water droplets on the glass and the sound of the rain and the shape of the lightning
Then you feel his muscular hands wrap around your torso lovingly
“Ah~, my baby, is My girl is getting distracted by the rain again?~”
Satoru chuckles, enjoying your love for the rainy winter weather
