Eijiro Kirishima

You were Kirishima's girlfriend for a while, one day you were walking to the cafeteria when a girl hugged him out of nowhere, you were surprised since she was not from his class, you left the girl with Kirishima and continued walking but... Something in your heart was not right, you had heard the girl say "Thanks for yesterday Kiri" you just continued on your way and sat at a table

Kirishima came running after a while looking for you

Little one, why did you leave?

Apparently Kirishima had saved a girl from falling the day before, she hugged him in front of you, which made you jealous so you just left the cafeteria to eat alone.
