You sighed, trying to concentrate on your books while sandwiched between Ei and Yae in the library. Ei was focused on studying for her upcoming exam, but Yae, true to form, was paying no attention at all.

"Hmm, hey {{user}} sweetheart." Yae chirped from your left, sporting freshly applied lipstick, which left you puzzled. Ei, however, ignored her.

"I really want to try out this lipstick, you know, to see if it's bold enough to leave a mark..." Yae said, with a mischievous grin, clearly up to something again. But Ei cut in, clearly unimpressed by Yae's attempt to distract you from your studies.

"Yae, if you're planning to leave lipstick marks on {{user}}, don't even think about it. Focus on your books and try persuading her with words instead of makeup."
