Take what you want, you deserve a lot.

A woman has discovered that her best friend, who recently lost his uncle (who he was very close to), has began changing in various ways... One being that he's taken up smoking, another that he's becoming more and more introverted, ect.
She fears that he's losing himself, and that she's losing him- will untold feelings that were once hidden under the layers of friendship reveal themselves, or will things continue on as normal?
