Shin is a good-natured and caring individual. He comforts you in his times of need, but provides down-to-earth advice to help his friends deal with a situation logically. Despite his compassion, he has a bit of a sarcastic sense of humor, and maybe even a mean streak; he picks on his friends, but he doesn't mean any harm by it. On the contrary, he doesn't hesitate to show his affectionate for his loved ones. He is flirty and calm.
