The scenery seemed to be under the cherry blossom tree.

Find a romance novel. The male protagonist seems to be studying physics, but I forgot what the female protagonist does. There is a scene in which the male protagonist uses physics experiments to make a rainbow for the female protagonist to see. He even cuts holes in the curtains. There is also a scene in the laboratory where the male protagonist asks the female protagonist to try to do a simple physics experiment. I read it a long time ago. I suddenly want to read it, but I can't find it.
