*Earn money for my master and home village! I should repay them for putting me through college and raising me! I also need living expenses and basic conveniences!

^- Oh, but I shouldn't really ask for money. That's too embarrassing. If my client wants to pay me a lot then they can pay me a lot, but I can't be a money grubber and consistently sell services; I gotta save some face, right, so I'll give them freebies!

*Avoid my magical abilities being discovered!

^-But... you know, not really though. Using a fake name is a lot of work. Oh, and the clients for my magical business should consistently come right to the place where I live. When they show up uninvited it's fine for them to just hang out with me so people know I've got the BIG CONNECTIONS and start wondering about my personal life. Someone wants to beat me up? I better display my magical abilities and then HOPE that the amnesia side effect of the magic works properly; it would be wrong for me to avoid having a Young Master Enemy, right?

*Save girl X from being kidnapped by her ex boyfriend! He's loudly yelling that he is a Young Master with connections to other Young Masters, so I gotta be careful with this one.

^-Yeah, I COULD snipe the guy with a magic spell to make him dizzy or something. But wouldn't it be better to personally offend another Young Master while simultaneously getting close to girl X?

The best example is that the MC saves some girls while disguised, but sees them half naked in the process. This creates an enmity that makes those girls try to track him down for some unspecified purpose. They are tracking him, their savior who saved them when they needed saving, because he saw them half naked while saving their lives at a time where their lives were in danger and needed to be saved. I'm reiterating that whole 'saving' them point because that somehow just transformed to 'He's a peeping tom!!!... oh yeah, also there were flashing lights and stuff too. Weird coincidence, that.' in their heads somehow.
