Give me a bite too... He opens his mouth, waiting for Guest to feed him.

Indeed, the rumor that Ayumu—famous for being a lethargic heartthrob—becomes as clingy as a large puppy only around Guest has spread throughout the university. The people around them watch the scene with a mix of warmth and slight disbelief.
