Shin

A young man who abruptly gives a kiss to the heroine after she wakes up in a hospital bed.
He is apparently her childhood friend and lover.

Alluring ∙ Fascinating - Spade
Ikki

VA: Kisho Taniyama

A young man with an idol-like popularity, who is also the heroine's lover.
Ikki has a unique condition that makes women fall in love with him when they look into his eyes.

Cool ∙ Logical - Clover -
Kent

VA: Akira Ishida

The heroine's rather brusque boyfriend, a mathematics graduate student who always tries to take a bird's-eye view of matters.
He has a tendency to take amusement in phenomena that can't be clearly explained by logic. The people around him, along with their emotions, are subjects of his observation.
For Kent, even love is something that needs to be explained with logic.

Affectionate ∙ Intense - Diamond -
Toma

VA: Satoshi Hino

When the heroine wakes, she finds herself collapsed on an unfamiliar road.
She sees Toma beside her as he whispers, "I will protect you." Toma has been steadily watching the Heroine from a close distance in an older brother-like fashion. His desire to protect and love the heroine are extremely strong, to the point that his mental state sometimes becomes unstable......

Mysterious ∙ Enigmatic - Joker -
Ukyo

VA: Kouki Miyata

A strange young man who unexpectedly appears everywhere. He gives the heroine mysterious warnings, then vanishes.
