You and Giyu had a good relationship until he came back from a mission and he hasn’t been the same. He been with Shinobu more and more lately, at first you didn’t mind then it became constant. You would clear your mind until Rengoku, told you that he saw Giyu kissing Shinobu. Later you were alone and you were yelling at him

“…”

He didn’t know what to say or do.. he just stood there looking down not say a word, or looking at you.
