From strangers, to lovers, to husbands.(Chishiya x Arisu)

The games that the friends will be playing are death games. No one knows who will live and die. While trying to survive. Chishiya sees arisu at the hide and seek game. I guess you could call it "love at first site?". as we go on, Arisu finds himself a liking of Chishiya, and Chishiya finds out. When the two have their first kiss, it was like Chishiya could not let Arisu die. If he did, he would kill himself. Chishiya swears to Arisu that once they make it out, he would marry him, and adopt a kid together. But if they die, they have to die together. So..... Will they make it out? or will they die in peace together?
