I've been playing this game for about 2 weeks now. I started with Kokoro and want to complete her collection. I'm currently playing as Tina trying to gift suits to Kokoro. I can give her love gifts the entire vacation and she never opens them. I just get "What could this be..I can't wait to open it." Her notes do go up, but she never opens anything. She has opened one suit in front of me and said she couldn't accept it or something like that. In about 20 to 25 hours play time: I've bought all of Kokoro's suits, used the cheats to make enough money to get the secret ticket, gave 2 of Lisa's suits to Kokoro in 1 vacation, and gave 1 of Tina's suits in probably 6 or 7 vacations.

If someone could please tell me what I'm doing wrong, I would really appreciate it.

Be patient mein freund. This game demands patience. I've tacked in 80 hours and just got Kasumi collection up to the following: Lisa,Ayane,Christie (only 3 more to go) and Tina's (3) million Z suits. Still trying Tina's yellow one for Kasumi.
As for Kokoro, try alternating from the cheap suits up to the most expensive.............I got her to wear the Venus, Arthemis and the other million Z suit(forgot its name.)

Are you wrapping them in Orange? Even if a girl hates you, after two or three love gifts she should start unwrapping them if the are wrapped in her color. Make sure you are giving love gifts, too, not like gifts.

Thank you so much. I'm colored blind and my brother told me the order of the colors of the gift wrap as you scroll through them. I guess I memorized it wrong. I've been using Gold wrapping paper.
Thanks again this has been really frustrating.

No problem, glad to help. Two of my kids are color blind too, it makes a lot of games a pain. A gift pattern that has worked well for me is, once her notes are maxed out, I give her a suit in the Morning. If she opens it, fine, if not, one more love gift during the same day, and one at night in the hotel, usually gets her back to max notes by the next morning, and I try again. I work from most expensive to least in order. This means I usually only transfer a few suits the first va-ca, and a few more the second. Most are then taken the third, and part of a fourth to finish it off. It's a little harder with the girls who don't like morning visits, and of course Christie, who only likes one visit a day. From mid-range priced suites on down, I frequently can get her to take two or even three a day. Good luck.

Buy one suit for each girl you're not using, wrap them, then hand them out at night.

The next day buy a set of the next suit to be distributed, then go hand out three love items to three different girls or play one of the minigames versus them.

If you get a suit returned to you that night (most will), don't open them, instead skip buying that girl a new suit the next day and resend her the ??? wrapped suit.

Spam them until they take them.
