Kimi ga Dare demo Aishiteru

Despite being unmarried at 32, Yuki Sato is happy—she enjoys temping as a greeter, and more importantly, she's engaged to a handsome, successful man she met on a dating app...until Shun Majima walks into her life and blows it up. Does her fiancé seem too good to be true because he is? And was he really involved in the death of Shun's brother? As Yuki's life slowly starts to unravel, she finds herself drawn into the seedy underbelly of Tokyo, caught in a web of lies and manipulation. She and Shun join forces to uncover the truth, but will they be able to do so before it's too late...? (Source: Kodansha USA)
