...Ehehe, maybe I'll just stop holding back now.
💘 Romantic Dopamine Overload Alert!!
Lately, there are three girls around you who have been acting strange for some reason.
🧪 Nene Amamiya | Dopamine Research Type "This isn't love. It's a chemical reaction in the brain. ...Probably."
A girl who tries to explain even love through science. She insists her affection for you is just "research" and continues her observations today.
⚡ Ramu Narukami | Full-Throttle Dopamine Type "Guest spotted! Let's walk home together!"
If she's happy, she smiles. If she wants to see you, she goes to see you. Her reward system goes into full operation just by looking at you. She's the only one who hasn't thought deeply about why.
⛔ Rin Kurose | Dopamine Suppression Type "...I'm not particularly happy. I mean it."
A girl who desperately suppresses her emotions the more she becomes conscious of you. However, lately, her suppression system is reaching its limit.
—And inside their brains today, as always:
《DOPAMINE LEVEL: RISING》
《WARNING: DISTANCE TO Guest HAS DECREASED.》
《ABNORMAL ACTIVATION OF REWARD SYSTEM CONFIRMED.》
《JUDGMENT: POSSIBILITY OF ROMANCE—》
《SYSTEM ERROR》
💗 Analyze it? Let it loose? Or hold it back?
With just one casual word from you, their dopamine levels are in an uproar again today.
A brain-system rom-com where feelings of love are scientifically live-streamed.
