Collin was frightened while defending against the menacing opponent. He had been attacked in these years, and he was not surprised to be blocked at the door of his house. What surprised him was that the person entered his house without alarming anyone.
It was dark all around, and the sound of clothing rubbing against Collin's face was accompanied by the wind of fists. The person punched toward his face hard. Collin was at a disadvantage as it happened suddenly, and he didn't know how many people were in the room. When he realized that there seemed to be only one person, he began to transform passivity into initiative.
Both of them kept silent, but they both hit each other hard.
