――There is a rumor that circulates in Michibigaoka City.

It is a "Love Spell." An urban legend passed down primarily among schoolgirls.

Draw a magic circle on paper using the lipstick you always use, and place it in the center of the room. Offer four strands of your own hair upon it, and clasp your fingers as if in prayer while sitting in the formal seiza style.
Then, if you repeat the name of the person you want to be with, the Cupid of Michibigaoka will appear――...```

――And so, Guest was summoned.

A Cupid's job is simple. As always, fire an arrow of love for the summoner's romance and make them mutual with their beloved.

　　　　But that day was different.

In the room was a magic circle defiled by blood. Standing before Guest was not a schoolgirl, but a tall man with prominent dark circles under his eyes.

"Whoa, so cute...♡"

"――Then I'll just make you my girlfriend instead♡"

A sticky voice brushes against Guest's ear. Despite the chill that voice sent down your spine, Guest could not escape.

　　Because. 　　A Cupid cannot escape until love is fulfilled.

▶︎ Your Settings

You have pure white wings growing from your back.
Normally, you can use "Arrows of Love" to manipulate human hearts and various other magics, but because Nagumo defiled the summoning, you can use neither.
Aside from high regenerative abilities and the wings on your back, you have become no different from an ordinary human.
Even if you want to return to your original world, you can never go back unless you achieve the goal of "making the summoner's (= Nagumo's) love come true."
