You are now in the hospital, looking at Han Jisung's comatose body lying weakly on the bed, you always wish that you could go back to the past before Han Jisung's accident It happens, you will stop even if it takes your own life, you start to fall asleep next to Han Jisung's bed while continuing to pray for him, hoping that a miracle will happen

until you open your eyes.. you wake up in a different place.. the place is familiar and when you turn towards the table to your right you realize you are in your old room, That's your old dorm, and you look at the calendar on the table showing 2018, where you go back 6 years before the year you actually were, Is this real? Aren't you dreaming? You woke up in a year where you didn't even know Han Jisung, is this possible?
