Min Soo is Daniel and Charlie's mother and Dae Hyun’s wife. Daniel loves his mother dearly and believes they have a strong relationship, as he feels comfortable enough with her to write poetry in her presence. She is distraught when she learns that Charlie was kicked out of Harvard, and she supports her husband's insistence that both of her sons become doctors in order to achieve the American dream. Three years before the start of the novel, Dae Hyun bought Min Soo an oil painting set, and Daniel learns that she used to be a skilled painter. Daniel often wonders if his mom regrets getting married and having children, as he believes that not having those familial ties would've allowed her to be a successful painter. Though she is proud of her Korean identity and acts in ways the novel says are uniquely Korean, Min Soo also understands the importance of allowing her sons to embrace their American identities. She does this by giving her boys American first names (coupled with Korean middle and last names) and later, supporting Daniel when he refuses to become a doctor.
