My Childhood Sweetheart Is A Former Yakuza Boss

I'm happy as long as Umeno is happy.

Umeno, who lost her love and her job, reunites with her childhood friend Kyounosuke for the first time in six years.
He was born into a gangster family but decided to live in the same world as Umeno. Now, he has left the family business and started his own company, working as a genius businessman.
"Why don't you come to my company and give me a chance to woo you?"
Umeno is invited by Kyounosuke to work at his company. But as soon as she arrives, Kyounosuke, who is said to be as cold and sharp as ice within the company, launches an extremely sweet and aggressive attack on her!"
