Wakana Chan39s First Sex — 190201no Watermark Exclusive

The romantic storyline technically begins in the home economics room. Marin, the gyaru goddess of the school, notices Wakana sewing alone. But the real trigger is the accidental run-in at the stairwell. When Marin sees Wakana’s sewing machine and casually asks what he’s making, he lies. He says it’s a costume for a doll.

A very pretty, very confident girl who smells like vanilla and laughs loudly.

This is his first intimate relationship with the opposite sex. He learns to measure her bust, waist, and hip while suppressing a decade of social phobia. The storyline here is brilliant: it inverts the typical “hot spring accident” trope. Instead of chaos, we get raw vulnerability from both sides. When Marin sees Wakana’s sewing machine and casually

As of the latest manga chapters (prior to the author’s hiatus), the romantic storyline has reached a fever pitch.
