Osananajimi to Sekkusu-gokko o Hajimete, 10-nen ga tatta

My childhood friend, Marikawa Haruhime is one of the most beautiful girls there in our school.

With that same Haruhime in question, we continue to play the game of sekkusu, a promise every Wednesday.

A heart-warming loose, flirty and a naughty love story.
