ok this is definitely BL, idk if i should continue or not.

It is indeed BL, but if you find it uncomfortable/hard to watch, you can stop reading this, no prob! (づ￣ ³￣)づ (no hate) but if you want to continue it's also okay, the story is great, but back to square 1

Friendly advice: You can check the "Top Tags" (not just the genre) first before reading if you're not into certain stuffs

i know now i did not know Shounen Ai is BL

Hey I think you should continue it if you have like it until now. Although is your choice.

i will, i like the story it's kinda a unique concept for me i might start to enjoy BL because of this

This is a good bl to start with! At least u arent jumping straight into yaoi which some can be straight up porn lol. I recommend global examination if u want to continue reading shounen-ai and want the same concept :)
