my favorite line is MC basically telling his dick: "I am smarter because i have a brain in my head, not an urethra like you".
The best thing is its title. It is self explanatory and immediately establishes itself as a silly gag manga, and automatically filters a lot of normies. I would recommend atleast reading upto chapter 4 where it starts to find its pacing.
Plot
A lot of the setting is similar to a very generic romcom highschool manga, but MC's dick turns into a girl (chienko) and she becomes a classmate / roommate pretending to be a relative. absolutely ridiculous situations follow with lots of dick puns. chienko is trying to make OP live a richer life with lots of friends and *eventually* get a girlfriend. We do have a lead female MC and although she starts as a cliche of strict studious class president, she makes for some great jokes with her reactions to absurd situations.
I caught upto current chapter 23, where we just finished establishing the core cast and having a beach episode with them. There are a bunch of silly jokes which made me laugh and honestly, i would say it is pretty decent.
