To Sir, Without Love: I'm Divorcing You II, Part 1 (light novel)

Byletta s marriage to Lieutenant Colonel Arnald Swangan started as a purely political affair, one she never desired and once hoped to escape as soon as he returned from the war front. However, despite their tendency to butt heads, the two have come to share a deep, emotional bond at least until the possibility of divorce arrives on their doorstep again. Between rumors, threats to House Swangan s estate, and a troublesome prince from abroad, what will happen to the love of Byletta and Arnald?
