K-Pop song addictiveness
K-Pop songs are so catchy that teachers actually start singing them during class, other songs don’t do that, like that one by Rosé and Bruno Mars or that one by VVUP
My teacher started humming 'APT' during the math lesson.
The principal joined in with 'House Party' during the CSAT.
My friend’s teacher danced during the test because of 'APT'.
