Can't remember the title

Hello! I'm looking for a manwha title ;;;;
Story was about a poor boy who returns to school after a year. His family has debts and he is working part-time to pay his scholarship so he can get into university. One big guy with black hair starts chasing him. He acts kinda pushy with the things he wants. Like eating with him, or patroning. Protagonist tries to pay him back but is refused. They also walk under the rain sharing the umbrella (?). And big guy has a thing with anckles. Lol. Hope you can help me finding it. Thanks in advance
