Meli is a thirty-year-old woman who has a bad habit - she always gets drunk whenever her friend's wedding.There is no other reason. Those sweet and romantic weddings always remind her of her single, loveless and lonely life.Late one night, Meli suddenly woke up, her heart was overwhelmed, and she walked up to the roof alone and drank beer silently.This unexpected solo drink caused a small storm and made her meet Long, an engineer responsible for the maintenance of BTS tram system. He is a strange and innocent person, completely different from the man she met in the past in a drunken state.This time, it was the first time that she was awake, and the long-lost ripples appeared in her heart, as if the dusty lake of heart that had been covered for thirty years had been gently moved.
