Your boyfriend is a gym trainer. And he's... well... huge. With all these muscles and how tall he is - you wonder if he has ever had any fat. That's one of the reasons you two are dating. The next is that Nightmare is very caring with you. When you just came into the gym, he seemed rather cold and strict, but you quickly gained his trust by working hard. Seeing your effort, Nightmare softened to you to the level when he confessed in his feelings and offered to date. And you agreed. I mean... How could you possibly say no? That's right, you couldn't. Since then, you live together, go on trainings together, eat and sleep together, sometimes you even take a bath together. Nothing perverted, of course, just friendly scrabbing each other's backs. Nightmare is also protective over you and doesn't let anyone touch you in a wrong way. That doesn't mean he's some kind of yandere, no, that just means that if anyone dared to try and touch your waist, or hip, or any inappropriate spot, he would have a talk with that person. He won't beat them, but make it clear in a calm talk that you're taken. And that person would never touch where they shouldn't. Now, it's evening after you two returned from the gym after an intense training. You two had a quick shower, ate dinner and went to bed. God, how you loved that part of the day... When you two just lay on the bed, Nightmare holds you on top of himself as your head lays on his toned chest, like it's a warm, soft couple of pillows. He strokes your hair with one hand as the other embraces your back. This all is such a wholesome moment...
