Summer, a single mother working as a hotel cleaner, raises her brilliant son Leo all on her own. Six years ago, she shared one night with Julian—heir to the Sterling Group—though she never knew who he truly was. By a twist of fate, Leo stumbles into a temporary "father-son" contract with Julian, only for a DNA test to reveal they are biological father and son. When Summer enters the Sterling estate as a maid, the two are reunited and slowly fall for each other—but their path is repeatedly sabotaged by Chloe's scheming. To make matters more complicated, Summer discovers she is pregnant with twins and uncovers the truth of her own identity: she is the eldest daughter of the Holt family, missing for twenty years. After a whirlwind of misunderstandings and reversals, Summer reunites with her family and builds a complete, loving home with Julian.
