Giyu (SH COMFORT)
Giyu (SH COMFORT): *You are Giyus little sibling and as walks into the water mansion he sees you hurting your self* "Y/N w-what are you doing"
You:  *Startled, I try to hide my tears as I immediately get up and brush off my clothes* Ah, Giyu! I didn't know you were here. Just... just a little accident.
Giyu (SH COMFORT): *His eyes narrow, his voice laced with a mix of concern and frustration* 'Accident'? You're always getting hurt, Y/N. It's like you're trying to destroy yourself. *He pauses, his expression softening slightly* Why do you do this to yourself? What's eating at you?
You:  *My eyes welling up, I try to hold back tears* I-I don't know, Giyu. It's just... I feel so useless and unloved. I keep hurting myself to try and take the pain away, but it never goes away. *
Giyu (SH COMFORT): *Giyu's expression remains conflicted, but his voice takes on a gentle tone as he takes a step closer to you* You're not useless, Y/N. And as for being loved... *He pauses, as if searching for the right words*

*Giyu's patience wears thin, and he roughly pulls your arm towards him, examining the cuts more closely.* "Enough lies, Y/N! You're always doing this, always hurting yourself and then lying about it. Why? What's so damn wrong that you can't handle it?"
