I feel more refreshed when the room is clean. The floor, which I haven't seen for a while, appears for the first time after a long while.

Hello, my floor. The last time I saw you was probably when I moved in here.

"Oh, this is delicious."

I take out the cookie from the box of confectioneries that turned out to be Wakamiya's wasted effort and chew it. Yeah, I can see myself getting addicted to this taste.

And then, the Goddess sat in front of me, her back straight. It's been thirty minutes since she had that posture. After flipping through her textbook, she copied something on her notebook, preparing for her study.

I also solved each question given by Wakamiya one by one...

"Ah, that's wrong. First, you have to solve this division."

"Haa..."

Her flat monotonous voice echoed in the small room.

For the first time in my life, a girl was visiting my house, but I didn't feel excited or happy at all...

When Wakamiya was teaching me, she became a scary person. She didn't accept any compromise... but well, she was good at teaching me.

"You shouldn't sigh."

"Ah, is it because a bit our happiness escapes from us every time we sigh?"

'Sighing will drive away happiness.' It's a very common saying. Either way, I'm sure I kept sighing because my happiness kept going away from me...

"It's a superstition. Rather, sighs are good for your health."

"Oh, I didn't know that. Mind telling me more?"

"Right, sighs help bring balance to the body... Ah, but we don't have to talk about this matter now."

"Tsk."

"Tokiwagi-san, you're not thinking of derailing the conversation to avoid studying, right?"

"No way. I won't do that!"

"You sound guilty, though. But for the time being, we can discuss sighs at a later date. It has nothing to do with our current study."

"Yeah..."

"Then, let's study English. You can't sleep until you memorized a hundred words today."

I dropped the cookie in my hand.

A demon...? Telling me to memorize a hundred starting now was the same as giving me a death sentence...

"Hey, why am I studying even though it's already late at night... Return back my sleeping time..."

"It's just past 22:00, isn't it? You also have to get back the amount of time you wasted by cleaning the house. You can sleep later."

"No, no. We can continue the rest tomorrow, right? You should go home too before it gets any later than this."

A girl was staying in a boy's house even after 22:00 in the evening. If her parents knew this, they would definitely get angry.

"It's fine. I will tell them that I'm going to my friend's house today."

"Isn't that the lie girls usually say when they're staying at their boyfriend's house?"

"That's also correct in a sense. I'm currently in a boy's house."

"Wakamiya-san, don't come to a man's house easily. Don't you think this situation is usually dangerous?"

"Not at all. I don't think it's a problem. I trust Tokiwagi-san. Also——"

"Hm?"

"I'm confident in my ability to judge character," Wakamiya answered. She puffed her chest in pride, making me unsure where I should look.

I'm happy that she trusts me, but... That also means that she doesn't see me as a man. I don't know what to say to that.

Well, I don't want the atmosphere to be awkward just because she's getting cautious or conscious of me too much.

"But you're right. Now that I think about it again, I feel like I'm doing something bold. Um, like going into the house of a boy of my age..."

"Aren't you too late to realize that..."

"Tokiwagi-san, do you think I am a nympho?"

"Why do you come into that conclusion...?"

"I feel like Tokiwagi-san is looking at me as an 'easy girl who doesn't hesitate to go to a man's house'."

"No way," I said, drinking the tea Wakamiya brewed. "But listen, Wakamiya. Man is a silly creature who has two brains, so... you have to be careful. It will be too late to regret it when a guy attacks you, you know?"

The most beautiful girl in the school. Divine beauty. The perfect girl.

It would be unusual for a guy not to feel strange when they were in the same room with such Wakamiya. She was fine since it was me this time, but it didn't mean everyone else would necessarily act like me.

"At that time, I'll admit that I don't have the ability to judge character. This is also a study for me."

Wakamiya had her hand over her mouth and smiled gently. I was charmed by her gesture, but I managed to calm down by pinching my thigh.

"No way, the risk of that study is too high!"

"A person can't live without sacrificing something."

"Deep! But you can't just apply those words in this case, you know. The damage is usually irreversible."

"Fine, I won't hold back today. Come on, remember these words."

"Why are you suddenly bringing that up!? The way you switch the topic is too rough, seriously."

I sighed and began to turn over the Goddess' handmade vocabulary notebook.

——One hour later

"I can't do this anymore. I start to forget everything..."

"I see... I guess forcing you to study any more than this will only backfire... It can't be helped. Then we'll stop here today. Tokiwagi-san, good work today."

"Ahh~...My head is so hot. It's like I'm going to have a fever."

I took a sip of the tea while dropping my head on the desk. This might be the first time I had used my brain this much in my life...

Next to me, Wakamiya was wearing her jacket to prepare to go home soon. She didn't waste any of her time doing nothing. She really had an unusually rapid pace in taking action, huh...

"It'll be a waste if we leave the remaining sweets like this, so please store them properly, Tokiwagi-san."

"Got it."

"I will come again next time, so please take care of me."

"Sure, if we have the opportunity. Anyway, thank you for today."

"No, we should help each other in times of need."

I sent Wakamiya near her house and went straight home without stopping by anywhere.

The house should have been dreary after we cleaned everything up, but somehow, I feel like the air is warm.
