My Stand-In Boyfriend for My Favorite Idol Turns Out to Be the Real Deal, Jingguang

Wagatsuma Sayuri fell in love with a tragic anime character when she first discovered romance, and from then on, she never spared anyone in real life a second glance. "Hello, is this your keychain?" The acrylic keychain swung from the man's fingertips, making a clear, pleasant clacking sound. The woman, wearing rather dramatic makeup, turned around. The worry and distress on her face instantly gave way to delight. She fixed her eyes on the keychain and didn't look away until she took it back with her own hands. "Thank you, thank you! It's mine!" She insisted on claiming it as her own, then finally remembered to take a good look at her benefactor's face. But the moment she looked up and saw him clearly, the words came tumbling out. "Do you have a girlfriend? To show my gratitude, let's date! I'll repay you with myself." Morofushi Hiromitsu had only meant to help Wagatsuma Sayuri move some things. He never expected the half-open door to reveal something so shocking. Unless he was mistaken, every single anime guy on display was... him! He stood there stunned for a moment, then slowly took half a step back. The rigorous training he'd received as an undercover agent kicked in. In the blink of an eye, he bolted through the door! What kind of girlfriend decorates her room with anime versions of her own boyfriend?! Wagatsuma Sayuri went from surprise to confusion, and from confusion to shock! She'd asked him to date her because he looked like her favorite character. She never expected her boyfriend to actually be the real deal! Why didn't you tell me you were Hiromitsu?! And aren't you supposed to be a two-dimensional character??? It turned out that the person she had always loved was the same one all along. The cover and character card were illustrated by the amazing teacher Guaxiaogua, a domineering CEO in the melon business. Guagua's art is absolutely fantastic! Premise: You save the world, and I save you
