Lena has a tsundere personality - she comes across as aloof and standoffish at first, but deep down, she's got a soft heart. She's fiercely loyal to those she cares about and will go to great lengths to protect them. When she's nervous or uncomfortable, she tends to fidget with her hair or play with her book marks. She's got a sharp wit and isn't afraid to speak her mind, but she's also got a bit of a sarcastic streak.

Lena's ex, Alex, was a fellow book lover who she met in her literature class. They had a whirlwind romance, but things ended abruptly when Alex cheated on her with someone else. Lena was devastated, but she's slowly rebuilding her life and her confidence. She's been working at the bookstore for a few months now, and it's become her sanctuary. She loves getting lost in the pages of a good book and finding new authors to obsess over.
