The next morning, Yuu acts like nothing happened. Miki is a little confused. The phone rings and it is Chiyako wanting Miki to wish Yuu a happy birthday for them. Then she hangs up. Miki is mad. She can't believe they would treat Yuu this way on his birthday. Miki is determined to give Yuu a birthday party. He reluctantly agrees to it.
Miki goes shopping and picks out pre-made food for the party. She decides to buy a box cake mix and make it for Yuu.
Arimi stops buy the Junk Jungle to wish Yuu a happy birthday and is shocked when he has the day off. Kijima explains that it is because their parents are out of town. Arimi then calls Ginta to tell him what is going on.
Back at home, Miki prepares the dinner. The timer goes off on the oven and she cautiously opens the oven door. The cake is perfect. Then it sinks. She was supposed to wait for the oven to cool down first. She fills the cake in with icing. After everything is prepared, she gets dressed up. Yuu comes down to a wonderful candlelight dinner.
Miki comments on the candles and notices that Yuu is staring at her. She gets a bit uncomfortable. Then she remembers that she forgot to give him a present. He stands up and takes her hand and says that this is the best present. He pulls her close, looks in her eyes and...
the doorbell rings!!!
It is Ginta and Arimi. Yuu invites them in for cake. Ginta realizes that it is just the two of them. He confronts Yuu. This is a pretty funny part of the episode. Then Rokutanda shows up. This part of the episode is also funny. Rokutanda makes fun of Miki's food and the others glare at him with laser eyes. You just have to see it.
Miki decides to have everyone play cards and she goes up to her room to get them. Ginta comes in her room. She makes him leave because it is too messy. He asks if Yuu's ever been in her room. She doesn't deny it. He then asks if she is wearing perfume. She tells him no, that it is the cologne that Chiyako gave her. He asks if it is for Matsuura. He then demands to go into her room. She tells him that he should ask to see Arimi's room. He tells her that there is nothing between them. He also tells her that if she tells him not to see her anymore, he would stop. But if she can't, he will continue to date Arimi.
