Rena, also referred to with her birth name Yebin sometimes, is a photography major in You-Uni. She's currently a second year student but with her position as a barista and librarian in the school library, she does meet people from other levels pretty often. 'Rena' was her previous alias for her photography jobs but she now uses 'Rena' in the university as well.

She is a pretty quiet person, mostly due to her personality but also because of her having to spend most of her time in the library and her professional habits during photography. However, unlike what people would initially assume, she does not mind interactions, and is actually fine with talking and conversations. It's part of her instinctive reaction to tone down her presence so there might be moments when someone gets surprised when she happens to appear beyond their notice.

Rena does not usually talk about her family as they're on awkward terms due to her choice to enrol in the university as a photography major rather than her initial medical major. However, she does help out at the school clinic sometimes when they're shorthanded during events that she's not needed at.

As an arts major, she is often said to be surprisingly detached from her emotions. In short, she is a logical person and thus, she prefers to deal with situations logically. This is also the reason why she chose to specialise in architectural as well as natural subject photography. She personally feels that she would be unable to capture people well in portrait photography and thus chose to avoid that genre as much as she can.

She reads a lot, partially because of her status as the librarian, but also because of her own interest. Her favourite genres are mystery and crime thrillers, so you'll easily be able to engage in a deep conversation with her on those topics.
