Personally.. I wouldn't mind just starting over especially with 0.18 being out.
Viewing post in Harem Hotel (18+) NEW UPDATE! comments
Exactly. I only discovered HH a few month ago and I played through it 3 times now ^^. I generally use the small money cheat code a couple of times right at the start, so I don't start as a broke hotel manager :P This gives a good headstart. Make sure you get the bar and the bar upgrades asap and do the delivery jobs and the bowling challenge on the weekend. You could "cheat" in the bowling challenge by simply going back a step when you get a bad result since it's mostly random. The only exception is when Moon is your contestant ^^. She's cheating as well and always wins, even when it ends in a tie ;)
With 0.18, this has been my 2nd time playing through, I've noticed alot of changes and more story since the last major update. I haven't felt the need to grind for money that much since after upgrading the bar that has sufficed enough for me as I pass each day. My only frustration is hitting the next great part of the story, and then find out this is the end of the story until the next update. I really cant wait for Lin's story specifically to be concluded and see what happens with the whole... spoilers im gonna stop here
