Welcome to Kdrama and Ramen!

A high schooler who grew up in a deaf family discovers a love for music.  And although he dreams of playing the guitar in a band some day, he feels guilty to his family, who can never hear or understand his passion.  So, by day, he is the model student who studies and acts as interpreter for his family members whenever the need arises.  But by night he secretly practices and pursues his love of music.  When a strange music store appears in front of him, he wanders in.  But when he leaves, he suddenly finds himself in the year 1995.  The first person he meets is his future father, who not only can hear but is looking for a guitarist for his high school band.  And when he finds out that the person his dad has a crush on is not his future mother, he decides to stay, join the band, and somehow make sure his dad and mom end up together.
