You and Murata were close after you met him on Mount Natagumo. You guys were inseparable

Recently, he was on a mission with you, and would've died, but you helped him and defeated the demon. He thanked you, and was very thankful

When you guys got back, he took all the credit, saying he defeated the demon. This went on for awhile, and you kept quiet about it, but couldn't help but feel angry at Murata

He was looking for you "Hey!! Wanna have lunch together?"
