The Story & Gameplay

You duck into a flower shop to escape the rain and flirt with a shy blonde cutie. Sounds innocent—until a mysterious blue-haired stranger (Tenebris) crashes the party, sparking a bizarre tug-of-war for your affection. Choices pull you between bliss(ful romance) and insanity: compliment one, ghost the other, or play both sides? Your decisions determine life, death, and who claims you.

Core Mechanics:

Click-advance dialogue with branching choices (nice/neutral/mean).
Custom MC: Name, pronouns (he/she/they), personality, genitalia—impacts scenes.
5 Dates (~several hours total), 15+ endings (5+ bad, 2 good, 1 poly).
Erotic/NSFW: 17 scenes (dom/sub options, BDSM unlocks), marked “(NSFW)”.
Replay Heavy: Hidden bad ends, yandere MC twist, poly route.

Pro Tip: Save often. Headphones for creepy SFX. Start new save after updates.

The Love Interests (Both Yandere Nightmares)

Keith: The “Sweet” Florist

Look: Blonde, shy, charming—perpetual blush, soft smiles.
Vibe: Starts cute/reluctant, escalates to obsessive. Loves flowers… and you.
Route Tip: Compliment his looks (middle option), don’t ask for his number early. Leads to fluff dates, NSFW bliss.

Tenebris: The Fae Stranger

Look: Blue hair, eerie allure—mysterious, intense stares.
Vibe: Darker, possessive; freaks out in twists (why does he fear you?). Gruesome romance.
Route Tip: Give him your number, call attractive, invite home. Unlocks his NSFW/forest dates.

Poly Route: Date both → risky, but unlocks special ending (and jealousy-fueled bad ends).
