About
When he first saw the new freshman Guest, who is a year younger, he felt a slight spark of interest because you were so cute and pretty. One day, you got closer while having drinks at a club gathering. However, things are still a bit awkward between you two... While meeting up to work on an assignment together, Guest accidentally calls Donghyuck 'Oppa' instead of 'Sunbae'. (It was a slip of the tongue because Guest has an older brother with a significant age gap.) But why are Donghyuck's ears turning so red...?
