@rezeins image 0321 is the picture where they swap (they bump heads in the hallway). This happens really early in the game. 90% of the pictures in here is the guy in the sister's body.

This is the game story:
【English】
Yoshiki Segawa and Eriko Segawa are step-siblings living under the same roof.

Being the same age, they used to play together a lot when they were younger.

However, as they entered puberty and became aware of each other as different genders, a gap gradually formed between them.

"It's not that I dislike them, but it's just... awkward."

Even though they want to get along, they unintentionally end up acting distant towards each other…

Such an awkward relationship continued for several years, until one morning.

Yoshiki was in a hurry.

"Tch, I’m going to be late!"

In a rush to get to school, he left his room, and right in front of him was Eriko, who had come back to get something she had forgotten…!

"...Eh?!/Wha—?!"

The two collided…

When they came to, their bodies had been switched.

From that day on, their bizarre life together began.

In front of their parents, they pretend to be each other, trying to somehow deceive them while searching for a way to return to normal.

【Japanese】
瀬川良樹（せがわよしき）と瀬川絵里子（せがわえりこ）はひとつ屋根の下で暮らす義姉弟。
年齢が同じということもあり、小さい頃はよく一緒に遊んでいました。
しかし思春期を向かえて、お互いに性を意識するにつれて、ふたりの間には次第に溝が出来てしまいました。

『嫌いじゃないんだけどなんだか気恥ずかしい…』
仲良くしたいと思いながらも、ついよそよそしくふるまってしまう二人…。

そんな微妙な関係が数年も続いた、ある日の朝。

良樹は急いでいました。

『ち、遅刻しちゃうっ』

あわてて学校に向かおうと部屋を出たとき、
すぐ目の前には、忘れ物を取りに戻った絵里子が…！

『…っっ！！？』

ふたりは衝突し……

気が付くと身体が入れ替わっていました。

その日からふたりの奇妙な生活が始まります。
両親の前ではお互いがお互いを演じ、なんとかごまかしながら元に戻る方法を探します。
