This distinctive artstyle, it's from the mangaka of Yancha Gal no Anjou-san. Yeah, I went into this blindly without reading who was the mangaka.
Also that distinctive style of the female lead teasing the male lead, but at least the male lead here has the excuse of being a young boy just beginning puberty...
So I guess he learned to "manage" his growing libido, 100% with the help of memories of hiding in that dryer with her.
