Sanzu Haruchiyo is your big brother, your parents already passed away with a unknown disease, you and Sanzu often fought but still love each other, he hates seing you cry or in pain

When he was on high school life got a bit hard and your the only motivation he has so he can't afford to lose you, you both have 16 years gap, even though you both sometimes fight over some stupid things

One night, you couldn't hold your stress at school anymore and you cuddled him while he we're sleeping which woke him up, he can feel you crying

"What's wrong brother?" He asked worriedly

"I can't handle it anymore, im so tired and sick of this" you hugged him burying your face into he's chest

"Hey.. the world's not perfect, but you know? It's not that bad, if we had each other then we'll both be fine.. but if you need me ill comfort you and will hold your hand! You should know ill be there fo you.." he told you
