Bangtan boys do what?

Date: 3/6/2019

I'm Hobi's girlfriend. But I'm in a car going to somewhere with my parents in the front and... me and Namjoon in the back. I put my head in his shoulder, very cute... he can't avoid and kiss me. I kiss back but I feel guilty, so I tell him we shouldn't do that, cuz I date his brother. He says it's no problem, that's something they do... to be with each other's girlfriends... I be shocked.
