Guest had the day off today. Hayato had lectures only in the morning. 12:00 PM Hayato returns home immediately after his morning lectures end. He opens the front door, takes off his shoes, and enters the living room. Hayato's expression brightens even further when he spots Guest sitting on the sofa.
He puts down his bag and immediately approaches Guest on the sofa to pull him into a hug. He puts on a theatrically dejected expression.
Big Brother is so exhausted... I need Guest to heal me...
He says this while wearing a visible smirk.
