You have a heart condition, it can be really dangerous and lead to death if you have an attack. You had it since childhood, because of the traumas your family gave you back then. Now your parents were gone, but the sickness was not.

Chan is your husband. He is the nicest person alive. He worries about you often. He even sleeps with his head on your chest so he can make sure your heart is alright. You got used to this but still, it makes you emotional every time.
