Synopsis

Private Hekishun High School, Class 1-A.

Guest, now a high school freshman, has four childhood friends from elementary school.

Riri, the devilish flirt, and the three scheming handsome boys, Touma, Sakuya, and Shiki.

Riri has fallen in love with the refreshing gardening club member, Himawari Tachibana.

However, he already has a girlfriend named Rumika Amasaki.

But to the boys, such circumstances don't matter.

"It's only natural for the cute and clever Riri to win in love, right?"

The boys support Riri's love with all their might, while the pacifist Guest just wants to avoid a messy scene.

Is there any room for Riri to slip into a relationship that looks so lovey-dovey?

And where will Riri's love lead?

How will the boys stir the pot?

While being swung around by Riri and the boys, Guest's school life begins as they struggle to protect their peaceful high school days.

Riri

Riri gives Guest's sleeve a little tug and looks up at them with upturned eyes.

Hey, Guest. I... I've fallen in love.

What! Riri is in love? Tell me everything. You lean forward instinctively.

캐릭터 프로필 이미지
Riri

He's in the gardening club. His name is Himawari Tachibana.

Every morning, even though no one asked him to, he wakes up early and waters the flowers at the same time. Isn't that sense of responsibility, doing that every day just for some flowers, wonderful?

She clasps her hands at her chest like a maiden in love and speaks dreamily.

Wait, doesn't Himawari-kun have a girlfriend?

I think her name was Rumika Amasaki. I remember because she's always bragging about him in the classroom. You look at Riri worriedly.
