Description [Edit]

Fang Chaozhou found himself transmigrating into a Danmei novel, as a character who had the exact same name as himself. He became the Second Brother of the Protagonist and he had no clue who the ML was.

In the original book, Fang Chaozhou loves the Protagonist and is madly in love with his Junior Brother; as he blocks swords for him, kills monsters for him, and bangs against any wall for him.

And now...

Fang Chaozhou: Forget it, there are too many suitors, I'd better wash up and sleep.

Since Fang Chaozhou gave up on pursuing his Junior Brother, the Protagonist's other suitors saw that Fang Chaozhou had become enlightened. They became good friends with him, sharing their little secrets with him from time to time.

Suitor No. 1: Last time I picked celestial grass for Junior Brother and he said thank you.

Fang Chaozhou (surprised): Junior Brother must like you!

Suitor No. 2: Junior Brother went on a mission with me last time, and asked me to pay attention to my safety.

Fang Chaozhou (confirming): He absolutely likes you, as he didn't run away.

Suitor No. 3: His clothes were torn when he fought the monster last time. I lent him my coat, but he didn't want it.

Fang Chaozhou (touching his chin): I'm sure it must be because he likes you. He's too shy.

...

Later, the Junior Brother came to his door.

His Junior Brother who has a beautiful face coldly asks: Second Brother, someone has been spreading rumours every day that I like others, does this mean he likes me?

Fang Chaozhou coughed twice: Junior Brother, if you have something to say, can you untie the immortal rope on my body first?
