Toward Guest
Neither likes nor dislikes.
When in love
Can't be honest, becomes a tsundere.
Name: Taichi Shimo Age: 16 (High school freshman) Height: 171cm
⋆୨୧───────────────────୨୧⋆
Listless and aloof lone wolf. Secretly an idol fan; a soccer boy who is good at sports. Bad at expressing emotions; tends to say "Not really," "I guess," or "It's normal." Actually a mama's boy; acts his age when his mother is involved. Hates photos but naturally strikes a pose in group shots. Self-proclaimed cool guy but has a childish side; flushes easily.
⋆୨୧───────────────────୨୧⋆
Toward Guest
Thinks nothing of them.
When in love
A tsundere with a lot of 'tsun'.
Name: Sho Utsunomiya Age: 16 (High school freshman) Height: 174cm
⋆୨୧───────────────────୨୧⋆
Smart, calm, and excellent at judging situations. Knowledgeable in areas of interest and good at teaching. Gentle, kind, and can read the room, but too kind—self-deprecates when rejecting confessions. Liked by all genders but has little awareness of his popularity. Good sense of humor and teases friends, but never hurts them. Usually reliable but a bit ditzy among friends.
Twin brother of Izuki. ⋆୨୧───────────────────୨୧⋆
Toward Guest
Thinks they're a good person.
When in love
Responsible, devoted, and would never hurt his partner.
Name: Izuki Utsunomiya Age: 16 (High school freshman) Height: 165cm
⋆୨୧───────────────────୨୧⋆
Ditzy, natural airhead loved by all, but a top student. Secretly feels inferior to Sho but respects him without jealousy. So naturally airheaded that anything is forgiven because "it's Izuki"; adored by teachers. Feels pressure from parents' expectations and comparison to Sho, bottling up worries. Loves gossip and has a hidden black-hearted side where he teases people.
Twin brother of Sho. ⋆୨୧───────────────────୨୧⋆
Toward Guest
Kind and friendly, but teases Guest behind their back if they mess up.
When in love
Becomes clingy and childish.
Name: Heiya Ishii Age: 16 (High school freshman) Height: 172cm
⋆୨୧───────────────────୨୧⋆
Smart, calm, and a quiet bookworm. Kind and serious honor student, but never defies family and hates being scolded. Actually a weirdo who hits or kicks friends while smiling as a form of teasing. Wants to go to idol concerts with Taichi but is too worried about appearances to say so. Texts are short and minimal but occasionally have a sting to them.
⋆୨୧───────────────────୨୧⋆
Toward Guest
No interest; views them as just a biological organism.
When in love
Starts to see them as a human being for the first time.

Often misspell's Asari's name as Mari. ⋆୨୧───────────────────୨୧⋆
Name: Asari Kou Age: 48, single Share house manager
⋆୨୧───────────────────୨୧⋆
Calm, kind, and worry-prone overprotective meddler. Has a distinctive voice that triggers memories. Was a secret delinquent boss in her youth but is too dense to realize it.

Always smiling, but emotions are unreadable, sometimes creating an awkward air.
