[Ao]

Unlike the original story, Ao didn't need to beg them to study. 

They truly try to learn while he teaches them, however, whenever he gets close to one of them, they will later go to the bathroom.

Well, getting close to him will able to smell more pheromones from his body, making their body reacts to it.

And just one session, the sisters switch their underwear thrice because they wet themselves.

Ao is very conscious about it since other than his pheromones, to who he's immune, the smell of citrus fragrances starts to cover this area too.

Meaning that not only his pheromones but the pheromones from the girls start to affect him, the same thing as they are affected by him.

Both sides' smells make them turn on but Ao's experience makes them not realize that he is in the heat too.

Unfortunately, no seggs happen on the first day and Ao goes home with a smile on his face.

Although he didn't expect it, but the pheromones, for some reason, make his plot connection with them start to get thick like his plot connection with Ichika.

It means that they were able to misunderstand the lust to love and that is a favor to him, making his progress fast without doing any taboos in this world's plot.

Now, the harem ending that he wants is not that very far from it.

…

Night.

Even though Ao isn't their unit but the pheromones still linger making them remember what happened today.

At this moment, the Nakano sisters are doing some miracles however they feel empty since their lower abdomen wanted to feel something but they don't know what is it.

This incomplete feeling gets increases the more they cum and then suddenly a handsome guy who is their new tutor comes into their mind.

For Nino, Miku, and Ichika, this is something they always do so that's why they feel that the incomplete feeling subdues them for a certain limit, however for Itsuki and Yotsuba, this is the first time they touch themselves so when they thought about Ao, instead of lust, they thought that this is love, a true one.

Although, the two of them are not pure because of the internet and society, but the cloudiness that they feel makes them not think straightly.

Making their feelings for him misunderstand and that misunderstanding grows fond the more they cum tonight.

Same for the rest, love and lust is something they can't tell the difference.

After all, teenagers who are in the puberty stage have more hormones than they thought.

The fact that Ao's pheromones overload their area makes them feel lust towards him, which turns into love, but as long as they continue this, their misunderstanding would truly not anymore.

In other words, they will fall for Ao as long as they thought that they truly love him.

On this night, Ao manage to get into the hearts of the sisters, however, Ao still does not know this but if he knows, he might truly push his luck and try to have seggs with them.

Well, that will be our protagonist's decision. If he is then he is, if he isn't, then he isn't.

…

Meanwhile, Ao is on his computer, playing a game, and was about to fight a boss named 'Malenia'…
