This was so cute and heartwarming. Grayson receives a heart transplant and after, his entire outlook on life changed. He asked his best friend to marry him as he had been in love with her before but never said anything because of his bad heart. Over the moon happy with his new life, he felt this aching sadness. He started to do some research on who donated the heart. Once he found out, he realized it was his high school sweetheart’s husband. He showed up for a visit and his pain heals once he sees her two children. The children of the heart donor.
