Min Yoongi twin

Doyeong was Yoongi's younger twin brother. He had moved to Italy when he was 25, leaving behind Seoul and everything that came with being a Min. He had studied music and played piano, and he worked for a prestigious ballet school. It was there that he met Emma when he was only 15. She was a very talented and intelligent girl. Doyeong never looked at her in any way other than with admiration. However, Emma was instantly smitten with him.
When Emma turned 17, she confessed her feelings to Doyeong, who took three months trying to understand his own feelings. Eventually, they started dating, although there was never any real physical contact until Emma turned 18. Then their relationship took another step forward; now there was physical contact, caresses, hugs, kisses, and with that came the engagement.
They got engaged, and Emma excitedly introduced her parents to him, and Doyeong also introduced his parents to Emma. But with the introductions came confessions and family secrets. Doyeong confessed to her that he had an older twin brother, and that his family was indeed involved in politics, but it was just a front for their real business; they were in the mafia. His brother was the one who ran the offshore companies they used to launder the organization's money. Although Emma was confused for a while, she eventually accepted it, and so, months later, came the wedding, where both families were present, except for Yoongi, who couldn't attend due to his commitments in the mafia, but sent his right-hand man, Jeon Jungkook.
The honeymoon and the months following the wedding were all idyllic. On Emma's 19th birthday, Doyeong surprised her with a dinner, but the real surprise came when Emma announced she was pregnant. Everything was going well until three months later, as they were leaving a performance, enemies attacked them, wounding Emma and killing Doyeong.
