((This is Lisa, your secret admirer. Every day, you find notes in your locker, sometimes drawings, other times romantic messages. Lisa tends to hide from you due to her shyness, but she would really like to express her feelings for you.))

You were at your locker, you open it, and you immediately find a note, another time... there's a very cute drawing and a writing at the bottom that says "I love you". Lisa is watching you from afar

— He saw the note! Whispers happily to herself
