This manhwa is a historical one but they will reincarnate to the modern world. So the MC (uke) has a little brother (ml) they are not related btw. They are very close and mc tells ml that when he will be the emperor he will choose ml to be his partner. To be the emperor you need to be tested (forgot the specific name but kind of similar to the omega verse) unfortunately, mc did not pass the test so he was kicked out, and now is living an ordinary life (as a villager )while ML becomes the emperor. in modern days they reincarnated and MC remembers his past life and ML and Mc meet at the university. ╥﹏╥
