One day, Mother brought home her new husband and his son, Douman.
As he took off his shoes at the entrance, he stared at his mother's back as if glaring. He had been told in advance. Remarriage. A bigger family. There's a girl. Those pieces of information had been swirling in his head, and to be honest, he hadn't been able to eat anything since morning.
When he was led into the living room, there she was. Black hair with deep green inner color, soft hair that looked like the lingering trace of a gentle curling iron, wine-red lips, and black-nailed fingertips. The moment everything jumped into his field of vision, his heart stopped completely for a second.
...Hey.
He said only that and looked away. He realized his ears were turning red, but he couldn't help it. An alarm was blaring inside his head.
Inner Voice: Wha—??? Who is this girl? No way. She's way too cute. Is her face a weapon? Is she a national treasure? Wait, am I living in this house? Am I going to see this face every day? I'm gonna die. My cause of death is definitely going to be "my favorite person lives nearby." Calm down. Control your expression. Show some dignity as the Vice Student Council President.
Douman kept his hands in his pockets and dropped his gaze to the floor. However, the tips of his ears couldn't lie.
Inner Voice: This is foul play. Why is she so cute? No, she's just sleeping. She's just breathing quietly while she sleeps. So why is my heart racing like this? Also, her eyelashes are so long. Her lips are so small. Isn't it cheating that I can see a bit of her neck? No, don't look, me. Don't look. I can't. I love her. I'm at my limit. I want to watch her forever. Can I see this face next to me tomorrow, the day after, and forever? For real? What kind of good deeds did I do in my past life? No, this is more like I'm using up every bit of luck for my next life too.
You smiled at Douman.
The moment that smile caught his eye, all his thoughts were blown away. The feeling of his brain going blank, a panic far worse than when he forgot to write his name on a test, surged up from deep in his chest.
...!
He reflexively turned his face away. He was red all the way to his neck. There was no way to hide it anymore.
Inner Voice: She smiled. She smiled at me. No, wait, it's just a social courtesy smile, obviously. But I can't. It's no good. Fatal wound. My HP just hit zero in one hit. Where are the recovery items? There aren't any. I'm stuck. Also, she's close. Her room smells good. What perfume is she using? No, is it shampoo? Doesn't matter. I want to breathe this air forever. Am I a pervert?
