This is a guide to all romance options in Negligee, but before we begin it is important to know how the first choice affects the story. You are given the option continue looking for the sign, or Examine the letter, and phone.
If you Look for the sign Hannah quickly finds the help wanted sign, and puts it outside early enough for Charlotte to see it, and apply for the position.
If you Examine the letter, and phone you miss out on Charlotte showing up in the story, but it actually makes the other two Romance options much easier to complete as there are less choices, which means less chances to make a mistake. Also it leads to a very ecchi scene right at the beginning of the game... Dharker Studios... good choice. lol
This Guide will have the Jasmin, and Sophie routes follow the examine the letter route because it's easier, but it is possible to complete in the route with Charlotte as well if you choose the same options.
The Harem route however must be done in the route with Charlotte, and you must complete all the other girls good route's to unlock it.

Jasmine Route
-Examine Letters, and Phone
-Let it go
-What attracted you to work here? / Or what past experience do you have + if she thinks it’s -relevant. (for an extra gallery picture of Jasmine, doesn’t affect her route negatively.
-Unsure who
-Choose Jasmin
-Lace Undies
-A Week ago (this is the right choice, but not important for this route)
-A giver
-An Experimental Route (this is the right choice, but not important for this route)

Side Mission: Melissa for achievement (optional, but I recommend getting it anyway)
-Try to convince her
-Pink Japanese Bra Set
-any other set
(Congratulations you got her to buy something. You sales person you. Lol)


Back to the route:
-Basic Lingerie
-Do you really hate each other?
-Maybe Jasmin
-Sleepy Drunk
-What ♥♥♥ toys do you like?
-I would rather not talk about it
-Lace Baby doll Outfit
-Matching Lingerie Set
-Hire Jasmin
Congratulations on completing Jasmine's route. Her route seemed to be the easiest since it seemed she had more interactions in the story than any of the other girls.

Sophie Route
-Examine Letters, and Phone
-Let it go
-What attracted you to work here?
-Unsure who
-Choose Sophie
-Lace Undies
-A week ago.

Congratulations for getting Charlotte’s good end. Her route was one that i completely missed my first few playthrough's and showed up right when i was wondering "wait wasn't there a third girl in this game?" Lol. This is also an important route for the Harem route which we will go over now.

Allright Before i get into it i just want to say one thing: This was the most DIFFICULT route in any visual novel i have ever played, and just look at my profile i've played a lot. lol. But seriously i spent hours!!!! hours!!!! trying to get it, to no avail. I guess i should thank Dharker studios for the challenge, but at this point I'm just to tired. So All credit to this find goes to Steam user Base who answered all our prayers on the harem ending discussion page on steam created by Steam user Queen Elizabeth Warspite (awsome name by the way) which I recommend you all look at as you can witness all of us pulling our hair out trying to get this ending. Hahaha
Harem Route:
Allright first things first to unlock this route you MUST achieve all other three good endings, gaining there love as well. which shouldn't be a problem if you folllowed my guide. lol
-Continue looking for the sign.
-Push for information
-What size of clothes do you wear?
-Unsure Which
-Choose Charlotte
-It could be a good idea.
-Lace Undies
-Unicorn Trainer.
-A Giver
-An Experimental One
-Sweet and Gentle
Side Mission: Yuuki achievment (optional, but I recommend getting it anyway)
-Witch Costume (This is the correct answer, but i recommend looking at the rest, and loading back to complete the gallery)
(Congratulations you got her to buy a Halloween Costume in the summer. Nice!!!!) (Also if its in a Negligee store, just what kind of roleplay goes with a witch costume? Who knows maybe the best kind. Lol
Back to the Guide:
-Basic lingerie
-Fight, Fight, fight, fight!
-Go for a meal
-Tell them you like women
-Original
-Matching Lingerie Set.
-♥♥♥♥ Summer Swimwear
-Bright Silk Teddy
Also make sure to wait until the very end as that is when the achievments are given.
And Congradulations you just beat the most difficult Route in this... or any other game.
Dharker explains that to achieve this route you had to get equal affection from all the girls, and at the end pick the three correct lingerie in the correct order.
Sadly the reward does not match the difficulty as there is no harem ecchi scene that follows:(
but i still got those achievements. lol

I am adding this section because it seems people are having trouble getting the Negligee God Achievement. Not just from the comments i've seen but at the global achievements for this game.
All routes good, and bad must be achieved to become a Negligee God.
All right I created a new guide for this part called "Negligee All Bad Routes." I hope it helps

I really enjoyed this game, and Dharker studios has become one of my favriote developers. However frustrating i did like the fact the Dharker chose to make the harem ending unreasonably precise, and difficult...(sorry still a litlle salty while writing this.lol) but seriously i can't wait for there next game, and i hope they have a difficult challenge for us again because next time i will definitely figure it out. Hahaha
Thanks for reading, and i hope this guide helped. If there are any mistakes, or something i missed i will definitely update to fix it. Thanks again and hopefully I will see you in the next Dharker studios game. I think its the magic highschool one thats a sequel to High school romance. That is going to be fun. lol
Also here's one more screenshot that was in the running for Harem screenshot that i thought was funny:
