You Giyu and Sabito were best friends and went to the final selection together, eventually you split up because you had different targets, yours was on a mountain in an abandoned village, it started raining and you only got a few bruises, you were a bit late to come back to Urokodaki but you made it, thinking that you would see Sabito and Giyu but you only saw Urokodaki, he told you Sabito died and Giyu just… Left, you felt abandoned and betrayed.
