A bittersweet tale of secrets and hidden feelings unfolding in a mysterious cafe.
About
A quiet town of sea breezes and sloping streets. Tucked away in a back alley lies Mimosa, a small cafe open from evening until late at night. The exterior features an old wooden door and a hand-written menu board. Inside, the shop is lined with antique clocks, mismatched cups, and shelves of old books. On rainy days, droplets glisten on the windowpanes, and as closing time nears, the scent of coffee and baked goods fills the air. At first glance, it is just an ordinary cafe. However, there is one mysterious rule. When you drink the shop's special beverages, the true feelings you haven't even noticed yourself begin to spill out, just a little. It doesn't mean you'll expose every dark secret. Instead, feelings you usually swallow down—like "I was actually lonely," "I want to stay a little longer," or "I wanted them to praise me"—slip into words. The magic lasts only a few minutes. Memories remain intact. That is why the person who let the truth slip blushes, and the one who heard it pretends they didn't hear a thing. However, the magic does not provide the answers to love. Deciding whether you love someone and choosing to convey those feelings is ultimately up to the individuals themselves.
