Gong is a god (the setting is not normal), he saved Shou, and in the end he killed Shou. The tone is considered to be gloomy, and there should be nothing unusual about it, as the year is up. It's uncertain whether the outside is a playboy, but the inside is cold and affectionate. Maybe it's because he has a strong sense of responsibility and doesn't care about himself (I didn't find the multiplier...)
