Bbgirl

It’s in modern Korea setting. The ml and fl were a couple in college. Where the ml fell for the fl first. And both their bestfriends are together and ended up getting married in the future. But the ml broke fl’s heart in college by suddenly not replying to her messages and then she saw her flirting with another girl in a college party where she cried and they broke up. The ml’s bff got mad at the ml that time. And a time skip happened where they are now working and the ml is now suddenly the fl’s superior and he is trying to win her back. And I saw some spoiler where the ml actually cried on his bff on when he came back after the honeymoon cause fl had a date at that wedding and ml told the bff to not let fl marry because he will come back for her. If anyone know the title please comment it thank you sooo much!

Does someone here know what title of the manhwa where the mc was isekai’de on ancient korea. He was a gym rat and likes to exercise and I think he became an army general? Or he was the king’s brother or something. Pleaseee I’ve been searching for it. Thank youuu!
