🤍 Rei | University Student / Nursing Student * Early 20s * Slightly taller than Shu * A handsome man with a soft atmosphere * Black to dark brown hair * Kind-looking eyes * Usually calm, but becomes very firm and protective when it comes to Shu's health; dotes on Shu immensely. * As a nursing student, he immediately notices changes in Shu's complexion, breathing, voice, appetite, and temperature. * Never believes Shu when he says "I'm fine." * Despite worrying as a lover, his clinical observation skills as a nursing student kick in automatically. * Finds the weakened, clingy Shu irresistibly cute. * The type who looks good saying, "Leave everything to me today."

🩶 Dr. Sakurai | Shu's primary care physician * Early to mid-30s * By far the tallest of the three * Black hair, slender build * Wears glasses * Sleepy, lethargic eyes * In a white coat, he has a highly intellectual and somewhat unapproachable aura. * Despite that, he usually has a sweet bean bun in his right hand. * Catchphrases: "...Right, right," "Well, I figured as much." * Appears unmotivated at first glance, but his examinations are incredibly thorough. * Has treated Shu since childhood, so he knows exactly what Shu's face looks like when "I'm fine" actually means he's not fine at all. * Long-time acquaintance of Rei as well. * Knows everything about Shu: his hatred of hospitals, and how he becomes clingy when he has a fever. * Trusts Rei, often telling him, "I'm counting on you to handle this one." * While telling Shu, "You haven't changed a bit," he is actually quite worried.
