## Description
Kei is living together with his elder sister, Rei. Their parents are working abroad so they are left at home, just the two of them. But instead of helping each other, Rei just bullies her younger brother, passing all the household chores to him and doing other nasty stuff when she's in a bad mood. She even bullies him at school (by taking away his lunch for example). Kei, just like the nice guy he is, however never complains and accepts all of the cruel things done to him. But all of this is about to change. One day, a foreigner girl starts attending their school as a new transfer student. She gets along well with Kei like she's known him long before.

## Characters
### Andou Kei (安藤 桂)
Rei's younger brother and a second-year student at the academy. He's average at studies but good at sports. Due to family circumstances (his parents are often absent, so he has to do housework, but his sister pushes everything onto him, leaving him no time for club activities), he isn't in any clubs.

He gets treated pretty badly by his hot-tempered sister, and while others sympathize with him, he still loves his sister. He has a gentle personality and is well-liked within his class.

Because he's good at looking after others, and due to his father's work, he lived in America for a short time as a child. Because of this, he is entrusted with looking after Linda.

It turns out he actually has S-type tendencies rather than M-type.

### Andou Rei (安藤 玲)
A third-year student at private Shirogane Academy. Her condescending and cold attitude at school makes her seem a bit isolated from others.
She's popular with boys but has few female friends.

She's quite intelligent, serving as the student council secretary, and isn't entirely without popularity. She's especially harsh towards her younger brother, Kei, to the point where others feel sorry for him.

She makes him run out late at night to buy sanitary products and even hits him (though she's not physically stronger than him).

Her father is often away on overseas business trips, and her mother is frequently occupied with work, leaving them to prepare their own meals. However, she dumps all the responsibility onto Kei.

Though she used to treat Kei as a stress-relief toy, one day, after her younger brother rebelled and she wet herself, she developed a masochistic streak.

Conversely, she ends up being trained by her younger brother, who has begun exhibiting sadistic tendencies.She starts deriving sexual pleasure from urinating in public.

### Linda Steigmeyer (リンダ・スティッグマイヤー)
AnAn American exchange student who came to the protagonists' academy through an exchange program. She was a cheerleader in high school and joined the academy's cheerleading club after transferring; she's a second-year student.

Kei, who ended up in the same class, takes on a sort of caretaker role and looks after her in various ways. She feels sympathetic towards Kei, who is always bullied by Rei at the academy.

While trying to comfort Kei, she gradually finds herself drawn to him. Being selected as an exchange student means she's reasonably smart. But she has an airheaded, natural-born character that hides it.

Her slangy English gives her a ditzy persona. Seeing Kei being teased by Rei at the academy triggers her maternal instincts, solidifying her feelings for him and putting her at odds with Rei.

She is over 5'7" with huge breasts and a toned body honed by cheerleading. She lived near Rei and Kei when they were kids in America and played with them.

In a way, she could be considered their childhood friend.
