I'm Acting Out My Sister's Life

Was a loveless contract marriage the problem? On the day of her sister's wedding, Summer is involved in an accident with her sister. "You're Winter. Summer is your sister." "......." "Your sister died in that accident." An expressionless face, a harsh tone, a blank stare. There was no affection, no love for my sister in the man's hard words. It was clear that.... "Don't be presumptuous." "......." "Winter, my girl." Since when? When did his eyes to me carry such possessiveness? When was my heart begin to flutter with every word he said? **Original Webtoon:** , **Official Translations:**
