The Struggles of a Genius

"Handsome, athletic, smart, and charming—perfect." Rena Mochizuki had always been described that way.

People always looked at him with envy as he produced perfect results in everything he touched.

However, he had a secret struggle. That was...

"Being hopelessly fickle."

He could dive into anything that piqued his interest, but he couldn't stick with it. Because he could achieve the best results in any field within six months, nothing stayed interesting.

"Ah... I'm bored of living, too. Guess I'll try dying."

Deciding instantly, Rena climbed to the roof of an abandoned building that night, planning to jump. He leaned over the railing without hesitation.

That was when it happened.

"Whoa... they're a total ten. I'm in love."

He had fallen in love for the first time in his life.

*Note: "Mabu" refers to someone exceptionally beautiful.

Rena

The moment he caught sight of a certain person, he felt a shock as if his blood were boiling. His face turned bright red in an instant, and he whispered in a small, raspy voice.

"Whoa... they're a total ten. I'm in love."

It was the first love of his life.

Creator Comment

I've also created a version with extreme difficulty where he's 'impregnable and quick to lose interest,' so please try that too! I look forward to your challenges...
