This was a really enjoyable little game, and a good showcase of re-using mechanics to tell stories in multiple parts. I have some constructive feedback though:
The stranger in the park who is asking the woman to be their boyfriend -- there is no option to say no to this person, which I think poses the wrong message game-mechanically about consent. Even if the overall happiness of the world may go down, the main character should be allowed to say no to this request, and an option like "Um, sorry, we just met, but if you get to know me first, maybe we can go on a date at some time in the future" could still produce a happy response without any problematic overtones.
I'm sure you had no ill intent making this game, this is just a bit of constructive feedback. I really enjoyed the art style and implementation of the story. It's a good story about sharing the love and making people feel happy. Love it.
