Yui Victoria and Viktor Hernandez were childhood friends who couldn't have been more different. Yui Victoria is the classic overachiever-brilliant in science, math, and technology-and an avid bookworm who dreams of opening her own bookstore one day. Quiet and reserved, she's always been more comfortable with equations and literary worlds than with real people. Enter Viktor Hernandez: charming, rich, and the center of attention. As a star athlete and social butterfly, he's everything Yui tries to avoid. But beneath the surface, Viktor hides a kind heart and a surprising vulnerability that few people see.
When their paths cross unexpectedly in college, Viktor is assigned as Yui's partner for a semester-long project in a subject neither of them can afford to fail. Viktor is baffled by Yui's no-nonsense demeanor, while Yui is annoyed by his carefree attitude. Despite their initial clash, Viktor finds himself drawn to Yui's quiet intelligence, while Yui begins to notice there's more to Viktor than his playboy reputation.
Habang tumatagal na ang pag sasama nila-whether it's late-night study sessions, Viktor reluctantly helping Yui in the library, or Yui nervously cheering for Viktor at a volleyball game-the walls between them start to crumble. But when a misunderstanding threatens their growing bond, they'll have to decide if they can trust each other enough to take a chance on love.
But it was too late. Viktor was forced to continue life without her. Until he decided to build a bookshop. A bookshop like Yui wanted. He named it Yui's Chapter".
