Tang Ye wasn't afraid of offending Su Li and An Ruoru. He was friends with An Ru and Su Li after all, so there was nothing wrong with speaking frankly between friends, right? Plus, he didn't want to continue causing Su Li to be upset about the previous incidents, so he decided to explain further.
He said to Su Li and An Ruoru, "I'm busy with some matters, and it's inevitable that I can't stay in one place for long, nor do I know when I'll leave, so please forgive me."
Su Li and An Ruoru didn't expect Tang Ye to suddenly explain so seriously, looking quite earnest. They exchanged glances, nodded, and Su Li let go of her anger at Tang Ye, saying, "Alright, I won't be mad at you anymore, lest it seems like you are my boyfriend. But I really do have a lot to ask you. Last time on Mount Tai, you saved me and Ruo Ru, and we wanted to invite you for a meal to express our thanks properly. You wouldn't turn down this bit of courtesy, would you?"
