The one manga

The One summary:

From ShoujoMagic: Lele was born into the fashion industry. Both her parents were models, and they both die in a tragic airplane crash leaving a 5-year-old Lele orphaned. Therefore, it is no surprise that Lele hates the industry, thinking it’s superficial and unnecessary! Raised by her maternal grandmother, Lele reaches seventeen years of age before she is sucked in when her mother's sister – a fashion model agent and former model, convinces the reluctant Lele to model. Lele had been adverse to the whole idea, until she sees a photo shoot of popular American model Angus Lanson, and she begins to see modeling as an art form. When Aunt Fei's magazine editor invites Angus Lanson to a meeting of all the top fashion ambassadors, a curious Lele is invited to meet him. She does not know that Angus' twin elder brother, Eros Lanson, is secretly accompanying his brother. This obviously leads to confusion and is the start of a charming story of Lele's goals: fashion in NYC, becoming a top model, and…love???
