“Ah, Young Master, Cassius?...I'm afraid you'll be dissapointed to hear that he's not available at the moment as he's 'attending' to his adopted mother in her room.”Cassius's lovely maid, Isabelle said in a fluster while she heard lewd sounds escape from her Mistress's room.“No, I'm sorry to say that you can't meet Young Master today, since he's 'helping out' his sister-in-law with some 'favours' in her garden.” The innocent Isabelle excused herself as she witnessed her lady's flower being picked, instead of the rest of the flowers in the garden.“I hate to say this sir but Young Master, Cassius is currently guiding Miss Knight in the 'ways of the sword', so you can probably only meet him tomorrow.” Isabelle once again blocked the guests from entering, knowing that the sword her Young Master was handling could penetrate a body, but could never wound one.“I apologise once again as Young Master is at the Capital right now teaching a class to the female students in the Academy.” Isabelle said with her cheeks flushed, already knowing that her master was taking a very 'practical' lesson about human reproduction with the girls in his class.“Oh my! The King wants to meet the Young Master?...Well I guess he'll have to wait since Young Master, Cassius has gone clothes shopping with the Queen.” Isabelle lied to the King himself, knowing that her Young Master wasn't shopping for clothes and was actually removing the royal clothes off the Mother of the Country.Excuses...Excuses...The loyal maid, Isabelle had no choice but to make excuses for her Young Master, who was the most talked about and hated noble on the Continent because of his depraved escapades with all sorts of woman ranging from his own Family to Royalty itself and his Tyranical rule over his estate.And to think that not too long ago he was considered a wastrel noble, who was going to drink himself to death one day....When did it all begin she wondered as she excitedly walked into his room to get the reward she deserved for being such a loyal made, while someone else made excuses for her this time.•°•°•°•°•°•°•°•°•°•°•°•°•[No NTR - No Yuri - No sharing - No system that assists the protagonist - No mind control - No drugs or potions that influence the girls - No unnecessary Drama - Incest - Harem - Hardcore Netori - Slice of Life Romance - Demigirls - Elves - Vampires - Beast Girls - Slaves - Royalty - Finally a very competent protagonist]
