The moment I opened the game, I was like "huh, this BGM is familiar, it sounds like from 7 years from now." and when I actually started playing the game and heard Daybreak as the BGM, I freaked out like, HOLYSH*T IT REALLY IS FROM 7 YEARS FROM NOW. Nostalgia hit me like truck. 

But I digress, the game was really good too. Wished it was longer though :'D

I must say this is one of the most beautiful VNs I've played; it's very well made too. It was very apparent how everything was made with so much care, from the design, characters, OST, and story down to every detail.

I love how the narrative implies a deeper story than what is portrayed, and the wistfulness of their interactions is unusually delicate to the point that it almost feels ethereal. Overall, it is a very lovely game.
