My Heart Beats For You, dear

Dean Rayden's character, Kindergarten Teacher known as Dream by his students, works as a teacher to help him feel better about his past. Romano Carter, the father of his pupil, Ayan, was someone he encountered daily.
As they kept running into each other, they could feel their hearts triumphing over their minds. When Dean learns the truth about his donor and their families, what will happen?
