He doesn't remember her, still he... T-T
Basically this happened. Souvenir was newly opened but due to its small area coverage, no one was visiting. She becomes a bit curious and visits the store, making Victor surprised. Even though he doesn't remember her, he still treats her to a meal for free. When she urges to not take it for free, he assigns the same bill to her as in the main story, to clean the plate. And leaves pudding for her with that note...
Let me tell you. In the first picture, Victor thinks that she is hitting on him and instantly turns it down. But in the later scenario, he smiles when he sees her enjoying the food and finishing it. Fate and Destiny, isn't it?
Bonus-
This is the graduation day of their batch in the police academy. After the ceremony, everyone rushes to their family, but Gavin had nowhere to go to. So, she introduces herself as her own cousin and puts the badge for him. She encourages him, but adding that those were the words from younger her. And, this guy is left like this afterwards. Just... Adorable so-
These time-memory events always makes me cry...
