At Elementary School, a boy (Ooyoshi from C-Class) asks Mikan out, but she turns him down to the amazement of her friends Sachi and Mami. The two tells Mikan she's very popular among the boys and ask her why she don't go with any of them. Mikan says that she is not interested in dating. So Sachi bring up that maybe the reason is she has an awesome brother. Mikan blushes telling its not true, but Mami notice Mikan' serious reaction and would meet her awesome brother.

Back at the house, Mikan thinks about what her friends said while Rito and Lala play each other on a wi-fi video game. Mikan then sees Momo compliments Rito for his game skill (obviously flirting with him) and this annoys Mikan which think Momo recently is too close to Rito and seems to be cluelesse on these things.

Later, Mikan confronts Momo about it asking her to distance from Rito for Lala' sake and stop to sneak into Rito's bed too wondering the reason. Momo jokes telling Mikan that she can join them if she would knwon the reason. Momo explain sometimes she is half-asleep and unintentionally end in Rit'o bed, but promises she'll be more careful. Mikan is not convinced and think Momo is looking suspsicious.

That night, sure that Momo have no intention to stop, Mikan sneaks into Rito's bed (while the brother is sleeping) to catch her before she came. However Momo don't shows up and Mikan looks at Rito's face with love thinking he's alwayas easy-going and make her work as sister extra hard. Mikan start to poke Rito' face and suddenly he grabs her butt in a dream about marshmallows. Embarassed from the situation, Mikan pinch Rito' face and he lets her go.

Mikan ask herself what she's trying to do here and think she should head back to her room. Suddenly a thunderstorm starts and scare Mikan who is scared of thunder and lightning. Rito, in his sleep, hugs Mikan and says its alla ok because her "onii-chan" (big brother) is here. Mikan remember like he used to does the same when they were kids and she was scared from thunder. Mikan realizes that the thing that calms her down is the smell of her brother and start to sleep.

The next morning, a confused Rito finds Mikan in his bed. Mikan tries to explain but is interrupted by Momo who snuck in Rito's room in the morning.
