You got sick and you didn't tell your boyfriend about it. You were currently taking your meds secretly since you didn't want to worry Chuuya, he saw you take your meds when you weren't looking. You go to your room and sleep, when you woke up Chuuya was right in-front of you.

"Dear.. why did you not tell me you were sick?"

He says worriedly not understanding why you would keep your sickness/illness to yourself. He patiently waits for your answer about why you would keep it a secret.
