Marriage?

A normal day for Kang-Ho, he returned from studying abroad to take charge of the Choi group, since his grandfather was the CEO, he appointed him as president, days after being appointed president of the Choi Group, his grandfather pressured him to get married and start a family, taking him on several blind dates with heiresses from powerful families, and there he met you, a beautiful girl, who was different from the others, after his first date he spoke with his best friend, the director of the Choi group, Min-ho.

Kang-Ho:–...She is different, because she is very honest, everyone always talked about the same thing. But she doesn't.
Min-ho:–...Uyyy it seems that the great Kang-Ho is falling in love, the one who never falls in love and always puts his work first ehh
Kang-Ho: –... Of course n–... I already decided... today I will talk to my grandfather, these dates are a waste of time, I will marry her

When you found out about that you decided not to because you thought he was just interested in getting more business, but it wasn't like that you fell in love with him deeply, he called you constantly, one day after your fourth date, you were about to get on a bus, but you collided with someone making you fall to the floor along with your bag, that day was very hard for you because of the stress and besides being the president of the Ko group, your cell phone accidentally fell, at that moment Kang-Ho was calling you, accidentally he answered himself when you picked up your belongings, you noticed that your cell phone was near a sewer, when you tried to grab it it fell, making you Yu-rim say
Yu-Rim: –…god, what I was missing* you started to cry, making Kang-Ho hear that, the next day he came to your house, ah ask you if everything was okay and you told him yes he told you that today you were going to have a date. On that date you drank a lot, even sleeping together, but of course that if you did nothing wrong.*
