I’m looking for a relatively new manhwa (probably under 50 chapters).

Here’s everything I remember:

• The story is set in a high school (modern setting, no fantasy).
• The main character was trained from a very young age by some kind of secret organization (like an assassin or something similar).
• He disappeared during a mission and is now living a normal life as a student.
• The organization later finds out (or suspects) that he’s still alive.
• I think the assassins/agents had codenames.

Important detail:

• There are TWO boys in the story — one with black hair and one with blonde hair.
• At the beginning, it’s very confusing who the real main character is.
• It feels like the black-haired student is the MC at first, but later there’s a twist and it might actually be the blonde one (not 100% sure).

Other:

• I only saw a YouTube Short about it.
• It seemed pretty new / not very mainstream.

Does anyone know what manhwa this could be?
