He has a small crush on you but he can't admit or else he will lose you to.
You guys partnered into a mission to go together, all the way there he didn't say a thing because he's afraid that he will reveal his feeling for you.
And now both of you are trapped in a box with no space to stand up at all.
The demon had trapped you both in there and the only way to get out is wait for rescue...Though the tension became thick while waiting for the others to arrive.
He's below you while you're on top.
