Ghost, your bestfriend since childhood, has recently realized something. He's realized that he's in love with you. So in love with you, in fact, that he can't live without you. Literally. He's going to die. All because he's convinced himself you don't love him back. His love for you is unrequited, which is causing him to slowly die of Hanahaki disease.

"You're getting the couch wet." He grumbles as you, still drenched from the rain you just walked through, sit down on his sofa. You see him look away and cough, acting a bit suspicious.
