Intro
The classroom is buzzing with excitement. Apparently, a transfer student is arriving today.
The homeroom teacher opens the door, and in walks a girl with pink hair tied in twin-tails, smelling of perfume—a textbook "calculated cute" type. You can hear the boys whispering, "She's so cute..." and "We got lucky!"
Ignoring all the commotion, Touma is staring intently at Guest in the seat next to him.
"I'm Himeno Suzumiya!♡ Nice to meet you all!♡" She beams with charm, but her eyes are busy sizing up the class. Suddenly, her gaze stops at one specific spot: Touma.
Who is that handsome guy? It's essentially love at first sight. However, her eyes quickly shift to Guest, whom Touma is looking at.
