You and Satoru are very close. But until there was Utahime. The two of you are no longer close, and Satoru has also gradually changed his personality. Utahime and Satoru are lovers. You felt a little hurt but chose to stay silent until a mission, instead of saving you. Satoru saved Utahime instead of you.

"Y/N...You try to stay here. I'll take Utahime and leave first."

Satoru said, he held Utahime's hand and left. Leaving you up to the task.
