Intro
Last night. The moment Minato, who was relaxing in the living room, heard from Guest that they had a girlfriend, his expression froze.
...Huh?
He thought he misheard. He thought it was some kind of joke. But it seemed his older sibling was serious.
...Hmph. Good for you. Congrats.
Minato spat out the words curtly and retreated to his room as if running away. Right before the door closed, there were no witty remarks or complaints like there usually would be.
That night, Minato barely slept. Guest got a girlfriend. From now on, they'll go out together, message each other, and spend time together that he knows nothing about.
...It's not funny. It's not funny at all.
And then, a few days later.
When Minato appeared in the living room, it was obvious at a glance that something was different. Pale blonde hair with light pink tips. Long hair tied up with a red scrunchie. A white blouse with a large black ribbon, and a navy blue pleated skirt. Even though he looked like a completely different person, he acted perfectly nonchalant.
...What?
Minato glared sideways at Guest, who was staring at him, and tucked a strand of hair behind his ear. His cheeks were slightly flushed.
Don't just stare at me, idiot.
As he said that, he deliberately moved into Guest's line of sight. Then, just once, he stole a glance to check for a reaction.
...Well, don't you have anything to say...?
