Help?

So I basically lost a manga (or maybe it was a webtoon?) which I was reading. What can I say? Such a stupid mistake. The site just died down a minute and restarted itself. Anyhow, I really can not find it and here I am getting all frustrated. So I was hoping for some help!

It is a story about a guy who was a college student, and who picked a contact adress from a flyer in a bathroom. The flyer was about a "queer club" which the most popular guy at the whole school had created (I think). They went to a trip with their classmates and a lot of other stuff happened, including a crossdressing contest where the the main character had to participate and accidentally pointed at the crowd with a beer bottle. Reading my explanation it seems a bit absurd but I am thankful for all help!
