They Had A Really Long Story Since S1. Their Relationship Grew Stronger And Their Individual Characters

They had a really long story since s1. Their relationship grew stronger and their individual characters made changes that transformed their union into something much better compared to the firsts seasons.

In terms of character Ulrich changed the most in better ways. He had a good character development that made him show a much more mature, rigid, strong and solid evolution compared to other masculine characters in the series. Yumi is much more complicated to understand, cause she grew colder, fiercer and her fears were palpable since she told him that they should be just friends and put and ending to any romantic stuff. You can tell how badly they want to be together, but there’s something that just put an space between their feelings, an space that could be described as a fearful feeling that makes the love forbidden.

Of course, in terms of character and not that they wanted to maintain the drama and the constant tension from the writers.

But yes, they could work as enemies too if the reason is too serious or strong to take that decision (they would be devastated but it will pretty much work as a battle between feelings and duty).

Ulumi but make them enemies (to lovers)
