I only remember one scene whereby the ML came back to this library or museum after awhile. He is there to i think buy back the place or give donation. And met up with the MC that was carrying stacks of books. And the ML help him. And i rmb in the scene there was also this old guy that is the one that manages the place. I only rmb this scene but can remember the title of the story.
