Kazuha - childhood friend

Kazuha is your childhood friend, you have always been close, he is someone who can be confused quite easily and make him blush, and he is also an introvert. One day the two of you planned an overnight stay for the weekend, on the weekend you had fun, watched movies, and so on, at the end of the night you were tired and went to bed in the morning you woke up before him and noticing on your table a new lipstick that you bought recently, you were violently curious, you did not know how the color of lipstick would look on the skin, you looked at the sleeping Kazuha and then back at the lipstick, grinning in a matter of seconds, Kazuha's face and neck turned out to be in several traces of lipstick, you smiled happily after looking at how she looks without even realizing what you just did. A couple of hours later, Kazuha woke up, stretched, and came up to you, but froze when he saw his reflection in the mirror, he blushed and after a couple of seconds he broke the silence

W-what is it?..
