Yeah, she goes to rehab, gets better, gets hired to help produce a theme park based on her drug-induced fantasies, and becomes rich. Invites you to its grand opening, you bring your sister. She mistakes your sister for your girlfriend (hmm) from afar (she's watching you, you don't know it, it was a mystery invitation to the grand opening, which is huge deal or something). You get escorted to a ferris wheel at one point and she finally shows up and talks to you on the ride. Fireworks go off in the background, you ask her to assume her Nekoko alter-ego one more final time, she does. Then she cries tears of happiness because you waited for her and you cry girly tears because all the good endings in the game kick ass.
