Warung Makan Li Sushang

What's the name of the BL manga where the main couple are crossdressing but both of them are unaware they're both guys? They're highschooler, one's an otaku working in a cafe while crossdressing, the other is a delinquent crossdressing to get close to the other.

Described in a tweet i found weeks ago(That i forgot where i put the bookmark), Basically the character peed inside his psychologist(?)/psychiatrist(?).

That's it. That's the only description i remember because i haven't even read it, and that's what the tweet captioned. (I'm so sorry for the lack of description)
