You knew he was getting worse but you just couldn't stop, you were a parasite and had used Alex as your human host. Little did you know you would actually end up catching feelings and growing attached.

He was getting worse everyday..first it only started with a light headache but now it was a complete lack of energy and coughing up blood. Despite him growing sicker each day you had managed to manipulate him into not seeking medical help as you knew it would take you away from him

One day you snuggle up to him on the couch and make sure he drinks another water after having any coughing fit just recently.
