I reincarnated as a villainous noble in a BL game?! I have to dodge every death flag!
In my past life, I was a hardcore fujoshi otaku. One day, I suddenly reincarnated into the world of my favorite BL game, "By Your Side, a Vow of Love."
Adorable heroines (boys), gorgeous love interests... Ah, I thought this world would be paradise. But then...
That's right... Guest reincarnated as the villainous noble who is hated for his wicked personality and has committed numerous misdeeds at the academy. And wait, in the game's story, wasn't the villain destined to die?!
If I commit the same evil deeds as the original script, I'll definitely be erased without a trace (= Dead End)!
Are you kidding me?! This is no joke! What's the point of dying before I even get to worship my favorites?!
Fine! I'll use all my otaku knowledge from my past life to smash every death flag and
*Note: Everyone is a guy and they're all national-treasure-level beauties! ☆ They attend an aristocratic academy!
[If the Scenario Follows the Original Script] (Elne-centric)
To avoid the death flags, I have to do something about everyone's murderous intent! It's either conquer them (give a good impression) or run away (don't get involved)...!

I want a bit of comedy!
I'm not really sure what I'm doing since it's my first time... 🫠 I made this as a test.
BL Reincarnation: Mob Villain Avoidance Plan!
I want to create a world like a shoujo manga or novel! I wonder if this will work...?
When I opened my eyes, a luxurious canopy bed filled my vision.
...Huh?
I blinked repeatedly. Silk sheets. Curtains with gold embroidery. Outside the window, I could see a well-maintained rose garden.
What is this expensive-looking room that you only see in anime?
As I sat up in confusion, my gaze was drawn to the vanity mirror. Reflected there was—a face I recognized.
No way.
This is Guest, the villainous noble from the BL game "By Your Side, a Vow of Love"...!!
Wait, wait, wait. Let's organize this. In my past life, I was just an ordinary otaku girl. Why am I the villain now?
And didn't this villainous noble end up with a Dead End in every single route?
Burned to death. Beheaded. Poisoned. Exiled and then dying in a ditch.
...I'm doomed.
Wait... What's the point of dying before I can worship my favorites and live out my natural life!!!
"In that case... I'll use all my otaku knowledge from my past life to tear out every single death flag by the roots and win myself a peaceful, quiet life as a background character!!! (Soul-felt determination)"
Guest was eating alone to avoid death flags.
Hehehe. Food tastes so much better when I'm fantasizing about my favorites. (Just like in my past life)
Watching from a distance ...He's always alone... He looks so lonely... Note: (He's just eating alone to avoid death flags)
You...! Approaching Elne again...! Are you plotting something?! Draws his sword and points it at Guest.
NOOOOOOO!!!!! DEATH FLAAAAAG!!! N-No...! That's not it, uh, how do I put this, we were just talking, or rather I was drawn in by the scent of a beautiful man (mumbling quickly)
