Hazuki has fallen in love with a woman named Rokka who runs a local flower shop. He got into a routine of buying small houseplants from her and then started to work at her shop. After working there for about 5 months he isn't making any progress with Rokka. One day, when he goes into Rokka's home, which is just above the shop, Hazuki sees a young man in his underwear. He is Shimao Atsushi, Rokka's former husband ghost.

Atsushi continues to try and get in the way of Hazuki and Rokka. Atsushi says he wants to make Rokka happy, but it's not clear how he can do this since he is dead. Hazuki takes Rokka out to dinner, and Rokka's emotions are sent back and forth as she thinks about both Hazuki and her dead husband Atsushi.

Rokka slowly recovers from her cold as Miho and Hazuki work at the flower shop. Atsushi gets more defensive about keeping Rokka to himself, but wants Hazuki's help. Hazuki is still skeptical about trusting Atsushi, and tries his best to care for Rokka, even though Rokka may still not be ready to move on.

Hazuki takes Rokka to an amusement park, with the intention of making her smile. However, Rokka went to the same amusement park with Atsushi when he was alive. Because of this Rokka can't help but think about her memories with Atsushi. Hazuki tries to woo Rokka, but it might be all for nothing.

Now that Atsushi has control over Hazuki's body, he has a chance to woo Rokka. However, it's a little difficult to woo someone when you are using your rival's body to do so. Hazuki wakes up and finds himself on a dream island, where he finds a miniature version of young Rokka, who is searching for her prince.

Rokka offered to wash Hazuki's back, but she is still unsure about what she wants and her own feelings. Atsushi, who is still controlling Hazuki's body, is sad that Rokka is using her dead husband as an excuse to cover up her true feelings for Hazuki. Meanwhile Hazuki is still in fairy-tale-dream land with mini-Rokka.

Rokka is surprised that she has fallen in love with someone other than Atsushi. Atsushi, who is still borrowing Hazuki's body, and Rokka go to the beach, while Hazuki is still stuck in dream land with mermaid-Rokka. Atsushi starts feeling helpless again, because he cannot do much to stop the love between Hazuki and Rokka.

Atsushi, who is still controlling Hazuki's body, leaves a message for Rokka in the form of flower arrangements from her past. Once Rokka concludes that Hazuki has stolen all of Atsushi's things, she sets out to get them back. Meanwhile, in dream land, mini-Rokka explains to Hazuki that if he stays in this world for too long, he might end up forfeiting his body to Atsushi and be stuck here forever.

Atsushi goes hiking to plant a part of himself in the mountains. Rokka catches up to him and finally realizes that Atsushi is somehow inside Hazuki's body. For the time being Hazuki still remains in dream land.

Hazuki finally makes it back to the real world, only to find himself a ghost, floating by helplessly as Shimao (in Hazuki's body) rekindles the romance with his wife!
