Moto Sekai Ichi'i no Sub-chara Ikusei Nikki - Chapter 16: Flashback

Working as a henchman for his childhood crush hasn't been great.

But Sam is a hopeless romantic. Even though she's a failed supervillain, he decided to work with her so that he can at least stay by her side.

Although things began to change when Kiara, his childhood crush, started developing feelings for a particular young man.

Now if it was just any other guy, he would've met with some unfortunate 'accident' already but the guy in question was none other than the son of the strongest superhero himself.

Starboy aka Anthony Willburn, the reason for all their failures up until now; and she decided to fall for THAT guy!?

Sam couldn't accept this absurdity and decided to ruin his love rival's life by embracing his destiny and rising as a supervillain himself.

Set in a distant future where only the chosen few are graced with superpowers, the story will mainly focus on the perspective of our protagonist as he will enroll in an academy of superheroes to get close to his love rival and find his weakness all the while maintaining his life as a supervillain.

Song Yuan accidentally picked up a 5-year-old child.

The child has bright eyes, chiseled features, and prideful demeanor. He referred to himself as “this prince” and his mannerism was wild, cool, and stuck up.

“This prince will never eat such lowly food!”

“How dare you flirt with other men behind the back of my imperial father?”

“He insulted this prince and you sided with him? This prince will sentence his entire clan to death!”

Song Yuan was very disturbed. The DNA test had confirmed that the child was, indeed, her son, but why did he act like he was delusional?

More importantly, who was the father of the child?

The prince was going mad from worrying; Imperial Father, if you don’t come soon, Imperial Mother is really going to cheat on you!
