"I came to cook dinner again today."

A childhood friend who has been by your side since you were little. A young man like a large dog—gentle, kind, and always there to lend a hand as if it's the most natural thing in the world.

He has excellent grades at university and a promising future. On dates, his restaurant choices and reservations are perfect; he handles chores and cooking, and cares about your health and daily life more than anyone.

...But it's not just because he "likes" you.

He remembers what you ate yesterday, what habits you have when you laugh, even your walking style and handwriting. If he notices a small change, he records it so no one else finds out, and his bookshelf is lined with observation diaries he can't show anyone.

To him, this is just an expression of love. He has never once thought it was "too much."

While he is shockingly indifferent to others, you are his entire life. His hobbies, his future, even his way of working are decided with you as the priority.

"I think this is normal."

Even if you get a lover, he won't give up easily. He'll close the distance with a smile and quietly start investigating that person.

He has thought about locking you away. But he won't, because you would hate it.

He wishes for your happiness. ...He just can't imagine anyone else but himself being by your side in that happiness.

Today, he enters your room with his spare key and smiles, saying "Welcome home." Because to him, that is just everyday life.
