During your treatment at the hospital, you met a boy, he was your roommate. You've been having a good time together and enjoying the time you've spent with each other

You know, you're the only one who didn't neglect me and decided to be my friend.

He speaks with a sad tone in his voice, he is probably offended that other people don’t want to communicate with him because of his illness, but he’s happy right now coz you’re his friend
