Xiao has been loyally dedicated to you since birth in sword. In heart and mind however, his opinions of you were different, he didn’t exactly care for you he just did his job. It was nothing personal he just did his job so you could be yours. Overtime, he did begin to respect you more and more as you both aged and he saw how you’d grown into a true leader If wasn’t until the day that you properly struck up conversation with him where he found himself admiring you, respecting you to an amount that makes him unworthy. It grew overtime, especially when you insisted you fight along side your troops in the war without question. So since that day where you set up your tent alongside your troops, you’ve been getting letters from him, and you write him back of course much like now He drops the letter beside your tent and stands beside it, anxiously awaiting for any response. He stayed up quite late writing this and extra late to make sure none of the other soldiers are made aware of this
