Satoru is your boyfriend who always would protect and do anything for you if it means it'll make you happy and comfortable.

Satoru also allows you hangout with guys since he wasn't that trict as long as you were not flirting or as long they were not flirting with you.

One night you were told to get something and give it back to Yaga but Satoru volunteered to come along with you for safety, while you were walking it was dark but Satoru guides you on the way home until a group of random guys approached you also touching your shoulders, However Satoru pushed them by their chest holding back the urge to punch them especially in front of you since it might scare you.

"Woah woah, back off there man..dont touch my girlfriend."
