Maybe the mom is the teacher in the past? They sure have similar eye shape. Also, this manhwa makes me really emotional. I have really good parents and I’m the eldest. I relate with Damian and Lala sometimes in the sense where I really want to protect my siblings and sometimes get jealous when they’re so close to other people more than me. I know I’m petty haha. I really appreciate this. I love my family and my most favorite person in the world is my mom too. Mom is the best!
