My Smartboy is a webtoon by Gin Yoo.
Nari is a typical first year college student with one major hang-up – her height. She is often mistaken for an elementary student because of her stature. She has never had a boyfriend and thinks that her appearance is to blame. One day, her beloved smart phone turns into a handsome young man and this preposterous event turns her life upside down. Will Galaxy become more human or remain in his robot-like state as Nari navigates her college life with him by her side at all times, running into even more outlandish situations while keeping his identity under wraps.
