The mc dated the ml's twin. (Mc is a beta? And ml is an alpha) The ml's twin eventually finds his fated pair and leaves the mc in front of the omega. The mc meets the ml and is scared to date because ml is also an alpha. Ml has the same fated pair as ml's twin but still stays with the mc.

Please lmk if you know this!

Plot: The mc crossdresses in undergarments which he borrows from his sister without her knowing(?). He crossdresses because he wants his best friend (the ml) to call him cute. In one part of the story the ml comes to the mc's house and the ml sees the strap underneath. It probably escalates from there. Ml reveals that he thought it was weird that he always thought the mc was cute so the ml started calling everything cute. In the end they both realize they like eachother.

Important: in school crossdressing might(!!) be included in a group of multiple stories

I've been looking for this story for a while now and I would be so happy if someone knew the name to this!

Looking for the source to this user's pfp! (I will forever be grateful)
