This is a weak ren day master with strong self stars but there is no resource star. Although the self stars are positive, the absence of the resource stars can affect a person's happiness because resource stars also represent the sense of comfort. So, her best luck pillar should be the metal resource luck pillar.
Xin-chou luck pillar will not be my choice because chou will destruct the chen stars.
