I find this rather fun. The premise reminds me a lot of Manual Samuel.
The only thing I have left to do is learn about the Triad's plans. The rest is pretty much done.
I found this mentioned on TVTropes. It is one of the most adorable VNs I have played. A bit too brief, but it was very sweet.
Also, I'm totally pretending that Time is gonna go for a three-way romance in the True Ending. Hope you don't mind it, hahaha!
