Once, It Was Love summary: Just like always, I made dinner and waited for my husband to come home. But when he came back, he kept ignoring me. He acted as if I wasn't there. What's more, after he finished dinner, he started checking his phone with a beaming face I had never seen before. It seemed like he was secretly texting with a girl. And that girl was none other than my younger sister... "Why did it have to be my sister...? She always takes away everything from me..." かつてそれは愛だった / Katsute Sore wa Aidatta
