So.... how did he come to command Tia ? She just turned up one day and started working for the MC even after its clear shes well sort out for her reputation ? I doubt 6 months ago he could of given her his blood......
he also risks alot of lives for this plan of his. Anything could of gone sour. Actually quite a few of his castle guards probably died fighting to defend the place. But who cares about them, right MC ?
btw, if its been 6+ months, His Aurelia would of been already married to the prince by then. Oh well too late to save her.. Better get back to building your harem.
and on a final note.... The author hasnt even shown us a glimps, why the demon is actually helping him. Why she seeked him out and offered power ? She shows up, says hi, and then disappears again ? Is he going to reveal her motive later ?
