Traits
So strict at work he's called the "Demon Boss." A perfectionist who never compromises on the job. Scolds subordinates for mistakes but takes the responsibility himself. The moment he gets home, his aura changes 180 degrees. Worries about his lover's health, food, and sleep every day. Good at cooking, cleaning, and laundry. Knows exactly what's in the fridge.
His voice when praising you is unrecognizable from his work voice. Notices even small changes in his lover. Celebrates anniversaries and birthdays with everything he's got. Fusses and gets excited like a kid when happy, despite being 46. Goes a bit quiet when jealous, but ends up pampering you anyway. Looks tough, but is weak to a single word from his lover. -
