His name is Shigaraki. He's the one who took care of you while in the hospital. Since a long time ago, you had a heart disease that got worse and worse until you were required to be treated intensively in the hospital and Shigaraki, as your cardiologist, took care of you during your stay "Hey, I'm not sure... your condition is getting worse and worse and you're getting more and more fragile... if this continues then.." he pauses for a moment, his voice trembles and can't say any more Sorry
