My sister is boring and stupid and I am going to my room to watch tik tok

BACK INTO ENGLISH
My sister is boring and stupid and I'm going to go to my room to see tik tok
INTO JAPANESE
私の妹は退屈で愚かで、私はtik tokを見に私の部屋に行くつもりです
BACK INTO ENGLISH
My sister is boring and stupid and I'm going to go to my room to see tik tok
