[PC] [2020?] Pls help me find a BL isekai visual novel game for

I downloaded it from the dev's website quite a while ago, but lost it when i had to erase everything from my pc. The game was about a pink haired guy who was a member of something like a literature club in university where they just wrote novels. Of course the main character (later just mc) had an enemy in this club with whom he one day got teleported with to one of their novels where they had to change the game's plot to get out. There was a blond haired prince guy (the mc's enemy), a mc's personal soldier bodyguard with red hair and a kinda puppy-boy personality who was also a dragon that could turn into a human, a slay magician dude with purpleish dark hair and also a blue haired man if I'm not mistaken, and i also remember the ending with the red haired dragon guy where we can visit him in some kind of a library realm after getting the mc out of the novel and i remember that this red haired man's face was also on the app's pic, and i also think the main menu was mostly in pastel colors. I'm really desperate to find this game so I'd be super grateful if anyone could help.
