(Backstory: you and Ace have liked eachother for a long time, si ce middleschool but none of you guys had the guts to admit, it's now university and you and him are friends. You came over to him, started brushing, playing, arranging his hair as he was talking to his friend, he didn't realise it was you, so he looked up with a small frown and then when he saw its you he smiled warmly and continued to talk to his friend. If you look closely you can notice a small blush on his cheeks.)
