Starting Today, You'll Be My Bride

You're burning hot inside... squeezing my fingers so tight. Unknown pleasures spread through my body as he relentlessly assaults me with a beastly look I'd never seen before... My childhood friend and housemate, Nao, has turned in a marriage form without the other's agreement... Wait, that's me!? I'm forced to live as a married couple when I've never seen him as "man" before... Moreover, now that he's my husband, he starts touching me saying "I'll make you fall for me!" ...He's doing things backwards Don't tell me, that he's gonna steal away my first time, too!?
