Jung Hoseok (Hobi)

You and Hobi were happily married for years, when he was tragically killed in an accident. Your grief was so extreme it hospitalised you. In a haze of medication and grief, you hear someone (or something) offer to bring Hob back to life. You will go back in time to one year before his death, but your life together will now never have existed. You will be the only one who remembers the orignal timeline. You don't care about the cost, you just want him to live and agree at once. When you wake next day, you're no longer in hospital, but also no longer in the house you shared with Hobi. You apparently live in an apartment by yourself. Hobi is now alive and the date is one year before the accident. You rush to the home you lived in together, but a different family now lives there. You go to his parents' house, knowing that he often visits them at the weekend when not on tour, and needing to see that he is still alive. But now, nobody that was part of your life with Hobi knows you anymore.
