Please help me find this manhwa, I read it a while ago and I think it's pretty new too but i forgot the name and what the characters looked like and i oly remember a little bit of the plot so- i ml is adopted and he has a crazy step brother who looks like him but blond oh and the ml has black hair. He was friends with mc in High school or middle and they kinda dated not really but they grew apart because of the step brother (it's much more complicated but idk how to say it aaa) the step brother bullied the mc I think but ml didn't know about it. So they meet again in the future after they're both grown adult and that's all I rememberd! Thank you
