I think they kissed, but that's it. They didn't go any further because uncle went out to the store to see his baby boy.
No lol. They only kissed then he went to go see his man #－.－)...
Why does he have to go to kiss a woman when he literally just had sex with the MC ヽ(`Д´)ﾉ I am pissed.
They aren't in a relationship yet (more like a fwb), so it's not wired that uncle could kiss others. He might still confuse about his feeling. Obviously, they both need time to think. Btw, it seems like in ch.21 they are in a good term now.
Wait a minute... How did he get lipstick on his lips?Did they kiss? Did they do anything else? I can't take it （/TДT)/
