What Is The Genre Of 'I'M No Longer Your Substitute'?

On the day Winter Everhart suffers a miscarriage, her husband, Joshua Stroud, and their son, Terence, are out with his beloved Jessica Lynch. They watch the very performance Winter has always loved. "You're just so unreasonable. What's the point of all this?" "Dad, can you get me a new mom? She's so annoying!" On Winter's birthday, she returns from the hospital only to find Joshua celebrating Jessica's instead. Even Terence, the child she nearly gave her life to bring into the world, pledges to protect the woman who has stolen everything from her. Tears glisten in Winter's eyes as she smiles. Then, with quiet resolve, she walks away from the cage of a marriage that has bound her for five years. Joshua and Terence believe she won't survive without the Stroud family. What they don't expect is that she rises so high that they can no longer reach her. "Mr. Stroud! Mrs. Stroud's car design is now number one nationwide—Stroud Group has been completely outshone!" "Mr. Stroud! Mrs. Stroud has just won the World Championship in Artificial Intelligence Design!" "Mr. Stroud! Mrs. Stroud has been invited by a foreign president to attend a state banquet!" Regret tears Joshua apart. Dragging Terence with him, he kneels before Winter and pleads, "Honey, please give me another chance! If being your servant is what it takes, I'll do it!" But just beyond the door, a strikingly handsome man kneels on one knee, a leather collar fastened around his neck. Twining a diamond leash around Winter's palm, he vows with his gaze burning with feverish devotion, "My master, from this moment on, I bow to no one but you. Please, take me in."

For three years, I played the role of a dutiful wife to my husband, Williams, until I found out I was just a mere substitute for his first love— the woman he truly loved.  When she returned, he threw divorce papers at me as if I meant nothing.  And when I refused to sign them, I was forced to donate my blood to his precious mistress, causing me to lose a child I never even knew I was carrying. Shattered and broken, I walked away with one purpose— avenging the death of my unborn child.  He realised his mistake, but it was too late. I was no longer his substitute, but a future he'll never touch.  “You were right, Williams. I was a substitute you never deserved.” 

I've accidentally worn a dress belonging to my deceased older sister, Gwendolyn Stokes, to a family banquet. Because of that, my husband, Thomas Torres, goes quiet with fury. He then sentences me to a punishment of kneeling in the snow for three long hours. The blizzard chills me to the bone. My son, Robin Torres, makes fun of me while hurling snowballs at me. "No matter how much you dress up, you'll always be a phony! Don't think you can go around replacing my mommy just because you've changed into her dress!" As I stare at Robin's face, which bears some resemblance with mine, I feel my heart breaking. He has no idea that I'm his actual mother. On the year Gwendolyn passed away, Thomas, who drank himself into a stupor, mistook me for her. That night, he kept moaning Gwendolyn's name and whispering sweet nothings to me. That was how I got pregnant with Robin. Thomas has forbidden me from telling anyone the truth. On the other hand, I can't bear to leave my own child alone. So, I beg Thomas repeatedly to let me stay in the Torres residence. During my stay here, Thomas gives me the cold shoulder all the time. Only when he needs to vent his desire does he seek me out. What I didn't expect is that Robin hates my guts as well. Not only does he keep pulling pranks on me from time to time, but he also curses at me. "Shameless women like you have no right to stay in my home! Once I grow up, I'll definitely kick you out!" Now, I can finally respond to him. "Oh, I don't have to wait for you to grow up at all." Tomorrow, I'll pack my things and leave. I no longer want to remain as someone else's replacement and continue living a life of humiliation. This time, I'm going to pursue a life of my own.
