That obsession is a dramatic/drastic remedy.

"I've devoted my entire life to curing you." I reunite with Minato, my childhood friend whom I parted ways with without saying anything, now as his attending physician. The cold, elite doctor he's become harbors a heavy, intense obsession that fills the gap of more than a decade. Frightened by that love, I flee and collapse from overwork, only to fall back into his hands once more. "I'll never let you go again." With him cherishing even the surgical scars that were once my complex, my body and heart melt away— A lifelong love contract between an overprotective, obsessive doctor and a frail, earnest former patient.
