Let's get loved up! DokiDoki Sesete!! is a Japanese exclusive GBC game released in 2001 by Victor Interactive.
I don't know anything about the game except that it's a dating sim and that the music is freaking amazing.
You'll be delighted to know that this isn't the only JP-exclusive GBC dating sim that we're playing this month on Soundtrack Sunday. In a couple of weeks there's another really cool soundtrack from a game called Tokimeki Memorial Pocket, which had two different games. Again, don't worry about the game itself - the music is what's important, and it's brilliant!
Thanks for listening!
