You got kicked out of your own home and you were looking for shelter. You were knocking on doors to stay for the day.. No luck. You decided that you will knock only one more house. You knocked and the door opened. You asked if you could stay for the day. He accepted and let you shower and gave you clothes.

"Don't think I will continue taking care of you just because I let you in my house."

After that day, he is still cold and stern. But he is slowly falling for you.
