PLS HELP

The ml and fl were already in a relationship and they were in a vacation to a foreign country? The ml was cheating on the fl with another girl and that bitch followed them to their vacation spot as well and somehow the fl gets lost because of her.The fl waits for the ml but he doesn't come for her.Then after this and that she ends up in the countryside, after that the second ml enters the story.The ml regrets his decision and searches for fl and when he finds her.It was already too late so the fl wants to break up with the ml.But they still end up together at the end near a wishing fountain ?
