Rio's manga / #Female knight(1)

Spoiler warning!!! the storyline in the beginning is really good but it gets so unsatisfactory once the they return to the capital. like 1) taking on 3 wives even though you love the mc??? 2) mc suddenly gets engaged and then gets her heart broke even though they just met like what 3) mc and the emperor get drunk confess and then mc ends up pregnant and runs.4) emperor never loves his wives and all their marriages end up as messes. all in all the last half isn't satisfying at all like why did they make nobody happy? i really loved the first half too
