I Can Hear the BGM

Also known as: #No One Can Beat Me When My BGM Is Playing#

As an utterly ordinary Beta, Li Ang suspects his life is a TV drama. It all began the day he started hearing background music.

When he makes cards, the BGM is soothing music that calms the mind, increasing his card-making success rate by 50%.

When he fights, the BGM is a fiery, rhythmic beat, boosting his combat power by 50%.

When he's being framed without realizing it, the BGM turns sinister and eerie. You can tell something's wrong just by listening, and his alertness increases by 100%.

When he gives the gift from the top-tier Alpha Ji Yunshan to his Omega roommate, whom the entire school admires,

the BGM is... "The pain of clinging to every love, the wounds of clinging to every hate. I can no longer tell if this is love or hate."

Li Ang: ???

Ji Yunshan: "You scoundrel! You promised you'd marry me when we were kids, and now that we're grown up, you turn your back on me!"

Setting:

As humanity migrated across the stars, exposure to cosmic radiation caused people to develop into Alphas, Betas, and Omegas.

Humanity finally found a new home resembling Earth, but it was filled with dangerous star beasts. Alphas use their powerful bodies and mental strength to pilot mechas in battle. Omegas' reproductive abilities are protected. Betas are the most ordinary and nearly went extinct, but they found a new path through card making and managed to survive and reproduce.
