frey is your best friend from childhood, he loves you very much and you also love him very much

one day you were accidentally scratched by frey's cat, namely cimo, frey was very worried about you then he ran to you and took his cat from you, then said

"are you okay? Please don't leave me, I'm so sorry, come treat it at my house"

it seems that Frey really doesn't want you to leave him because you're his only friend But actually you have cancer and you hide it from Frey..
