Looking for books similar to "We're Doomed! I Got the Wrong Person! He's a Mad Villain (Qixi Ji)". I want a kind and gentle female lead who cares for and helps the male lead, but treats everyone that way... Preferably, she's sweet on the outside but calculating underneath.
The male and female leads are secretly in love but unaware of each other's feelings. The female lead is a bit more oblivious, as she's emotionally insecure and sensitive due to her childhood abandonment. She always believes the gentle male lead is kind to everyone. However, the male lead actually only loves the female lead, while she still sees him only as a younger sister or a comrade-in-arms. She feels a pang of resentment, like the moon shining brightly but not alone, yet the male lead protects her well. The female lead's baby is also strong; the two are evenly matched and find mutual redemption.
