The Man's Tag is a book made by Eunmi and Arin that labels the guy into their own tag - The Playboy, The Puppy, The Leader and etc. The new student from LA need his own tag as well so Arin figures it out while Eunmi is struggling to get that one short guy a tag. What if it is all an act of reasoning just to be close to the new student, Joshua and the Secretary of Student Council, Jihoon?
