I kind of wished the manhwa kept the pacing of the novel because how the characters interact with each other seems to have more depth.
It is particularly obvious with Ran's arc, I was curious when Ran was going to be hired as the 4th retainer but the timing is completely switched with this one... (it happens far earlier and the situation is expanded even more) Eyra isn't the one doing the main investigation, but his other retainer who wants him to rest. His arc is heavy on the aspect of gaining trust and I loved seeing the dynamics Eyra had with them since building a successful estate isn't a lone effort. Plus, it was really great to see Eyra able to succeed and his loyalty despite being forced into the situation really shined in the source
I started noticing it even more in the most recent chapter because I don't remember seeing that "become my mistress" interaction in the MTL novel haha... Funny change but I think I may have a hunch who this is...
