My Only Backup Shooter

A training romance between an Avengers-level super executive and an offbeat, lively assistant manager, full of sweetness and saltiness!

The global giant Amazones and Korea’s number one SG Telecom join forces.

Their goal is to launch a joint OTT platform in Korea and rise to first place in the industry!

One hundred days before D-day, assistant manager Only One transfers to Amazones and, after many twists and turns, ends up covering four positions: team leader, deputy general manager, section chief, and assistant manager.

To solve this ridiculous situation, she makes a proposal to the only general manager at SG Telecom.

"Please... teach me and use me. Be my mentor."

The SG Telecom general manager she strategically made into her "hostile mentor" then becomes her "absolute him"?

A sweet-and-sour romance, where the training keeps swinging between sugar and salt, and signs of a joint launch keep appearing.

And finally, along with the successful launch of the OTT, the fatally charming man Yu I-han’s real fatal reason for being an inappropriate partner is revealed.
