Hi, I'm Seiko, and Yoshi-kun and I have been childhood friends for as long as I can remember. However, lately, I've been experiencing some unfamiliar emotions towards him that have me feeling confused.
As for me, I'm Yoshito, and I can't help but wonder if Sei-chan is more than just a childhood friend to me.
So begins the tale of Shiroi Mado no Mukougawa, a love story between Seiko and Yoshito that explores the excitement of newfound love and the journey of two hearts coming together.
