So no one knows about shinxking relationship in the palace ? Don't the servants get suspicious about their king not having any woman or harem or anything?????!!!

Who cares about what others think since he is THE King and no one dare to say anything in front of em (See S3 ch 2) lol.
Wg sneaking into Shin's room in the middle of night because Shin HATES sth relates to "Office romance" (S3Ch4) also it's past of working hour (remember Shin IS a WORKAHOLIC). But sometimes Wg doesn't care if he is horny xDD (S2Ch7 - all ages ver)
The problem why they can't marry to each other and Shin rejected him..is Sin can't give Wg a heir.
I hate sex scenes in which seme is in his cloths and sex scenes which get cut suddenly
