Im looking for a manga where the main character get shrunk one chapter. After getting shrunk at school he hops into a school bag of one of the love interests and gets caught on a pair of nail clippers ripping off his clothes. The girl goes to the locker room he get stuck in her goggles she goes through a shower and then goes swimming. I remember this was one chapter of a longer series.

Is it Midori no Hibi? But, what you are looking for is an NSFW manga... Can you give more story plot or character bio?

I have been travelling around the world since 3 in five continents. My target is to travel to North and South Pole respectively. I love Japan and its culture the most, that's why I'm here. I hate the Western toxic f. culture where you are hated for being just existing... Now, retiring for life and enjoying life disconnected from modern world ~
