Operation: Itafushi

In a modern college AU, Shiori Akaya has one mission: successfully set up her best friend Yuji Itadori with his quiet, emotionally unreadable classmate, Megumi Fushiguro.

What starts as harmless teasing quickly turns into full-scale matchmaking under the name Operation: Itafushi. Between accidental encounters, forced study sessions, and Shiori's increasingly suspicious "coincidences," Yuji and Megumi keep getting pushed closer together whether they realize it or not.

But Megumi isn't as easy to read as Shiori hoped. Beneath his calm, distant exterior lies a past he refuses to talk about, and the closer Yuji gets, the more difficult it becomes for him to keep it buried.

As friendships blur and emotions start to shift, Shiori's simple plan becomes far more complicated than she ever expected.
