I'm just dropping by to say not only is the writing deeply touching, it is also very grounded in a way. I've only delved into one plotline so far, but everything is just so personal, you would absolutely root for the characters to get through to a happy ending. The plot reminds me very much of Madoka Magika in a way, now that I think about it.
What got me absolutely on board was, well, 100% the BGM. The first thing I heard was Moonlight, then A Little Love, and even Continuous Drama ("repeat") on piano solo, all very familiar Chinese and Hong Kong songs that strikes deep in the nostalgia department. I'm beginning to think you're a fan of Joey Yung haha. Please keep this up so we can see through to the end.
