"Shut up and leave everything to me." The only healing for Mikoto, who is busy with work every day, is the visits to the aquarium. One day, her attention was caught by a male diver swimming gracefully in the aquarium. She realised it was her childhood friend Kite! Growing up he was poor, but now he's grown up to be a handsome guy... The tension is high at their reunion, and it was okay until she went out for drinks together with Kite, but she got drunk... She woke up next to Kite?
