Once there was a young student named Rui Kamishiro an astronomer who loves to see the stars and hates eating vegetables and also loves inventing things, some students see him as a "weirdo" and could never "be himself" but there is one student that couldn't see him as those and that's Tsukasa Tenma who's also a young student that is loud and very energetic that secretly has feelings for him.

Rui was busy inventing something that could be seen very visible when using his telescope, as he's working with it he lost one object that very hard to look he was struggling on finding it he looked under his table, behind his invention that he's working with, under his chair, under his carpet etc. Rui was exhausted, and he would think that he could give up, but he didn't and thought that if he dropped it might go rolling outside and someone could've stolen it. So he went outside and started to ask some students if they got the object he was looking for.

"Excuse me have you seen a transparent circle rolling around..?" Rui asked with a slight nervous tone.

"No I haven't I'm sorry" The student responded with a calming tone.

Rui nodded and continued to ask and look for his lost object. Until now, his friend found it then began running towards him and asked if the object he was holding was Rui's.

"Rui!.. Are you looking for this? I found it.. And it has a light scratch.. I.. Accidentally stomped it lightly, but I could change it if you want..! haha.."

Tsukasa was feeling guilty and sweats as he's looking at Rui with a nervous look.

Rui was silent as he was disappointed but he didn't want to upset his only friend, so he breathed in then out and spoke with a calm tone.

"It's okay Tsukasa it's just an accident no need to replace it I could fix it myself"

Then Tsukasa was relieved and had an idea.

"Is it alright if I could help you?" he spoke with a cheerful tone with his eyes sparking.

Rui then widened his eyes and thought if this would be a good or a bad idea. He wanted to decline it because he doesn't need anyone's help but on the other hand, he wanted to accept it because it's his friend.

As decided by Rui, He accepted it and patted Tsukasa's head like a cat. Tsukasa got so excited and screamed very cheerful and loud but, Rui told him not to be so touchy on his things and unfinished inventions and be so helpful towards him.

Tsukasa then agreed and hugged him tightly as they first worked on their classes first, after class they both finally walked but before going on Rui's place they decided to eat at inside a restaurant and talk silly things, petting cats and many more.
