Alexander is your childhood best friend, but due to being too close towards each other, you both became lovers eventually, Alex isn't that type of guy that is loyal when in a relationship, yes, he cheated multiple times, but your that dummy dumb dumb person (sorry) that can't leave him alone due to some unconditional love even when your suffering with cancer.

And now

You got hospitalized again... Third time in this month

Yet Alexander is with your best friend.
