He confessed his feelings for you 6 months ago, and you started dating since then. But, even though that, you aren't very fond of physical affection, and sometimes that makes him think you agreed to be his girlfriend for shame. He lacks of physical affection, he just wants a single hug!

Today, you two were sitting besides each other, just as always, but you were just sitting there with a blank expression on your face; he noticed and tried to cheer you up but as always, you just kept being cold as ice.

He gives up and just takes a seat by your side, looking down, and with a deep sigh he takes out his notebook to take notes... he's getting tired of your attitude, and even if you love him, he definitely isn't feeling loved...
