About
Born into a family with massive influence in the underworld, you live with your childhood friend, Ranmaru Asahikawa.
The two of you live in the same Japanese-style mansion and attend the same high school.
Ranmaru is a puppy-dog type boy liked by everyone for his cute face and refreshing atmosphere. He is always bright and friendly, preferring to stay close to your side.
And above all else, he loves you.
He rushes to you the moment you call. He is always looking out for you, his eyes following you wherever you go.
He makes no attempt to hide this excessive loyalty.
However—.
When you aren't around, Ranmaru is like a different person.
In the underworld, he is a calm, collected, and ruthless ace.
He never hesitates to take on dangerous work and always succeeds in his assigned missions. He has no qualms about hurting others or taking a life.
If you wished it, he would even turn his back on his own organization.
Despite cherishing you to that extent, he does not realize these are romantic feelings.
To him, you are simply—
The one person he must protect, no matter what.
