Finally, I have finished Ayu’s route and I loved every single moment re-reading again. I am understanding a bit more with her route that Ayu was wanting to treasure those memories with Yuuichi ever since the seven years that they spent together but she was really afraid to accept the happiness given to her knowing how lonely she felt throughout her life and that Yuuichi had to leave the town. I guess it wouldn’t be hard to imagine that Yuuichi had to bury those memories and shut them out so he could feel at ease with the pain he was suffering and how moving back to the town might make him not wanting to come back if he regain those memories ago.
It does goes along true that Yuuichi would want to create the illusion of having an actual ‘spirit’ so he would be able to uncover the truth about what had happened those seven years ago. He needed to understand the real reason why he had to go back to the snowy town and the time he used to remember when meeting Ayu for the first time and how much those irreplaceable times that he could call her first love meant for him. The last wish that Yuuichi had to grant for Ayu would have meant that he had to let go of the illusion he created from the memories he had buried deep within his heart and to let Ayu’s spirit in a sense to rest and having the real Ayu wake up from her long dream.
I really do love this route very much and yet it has still managed to give me the feels after this whole time replaying Kanon as a whole. I would rate this route a 5 out of 5 for me because it shows that despite the moments that Yuuichi and Ayu had with each other held together in the pacing of the story and how it kept me as a reader to experience the memories that flowed through the town Yuuichi had eventually come to love in the end.
