Our Cool School~! 4 ''I Have Proof! He Was The One Who Did That!''

Li Yuri was packing her bag when someone pulled out a chair in front of her. It was Tang Min. ''Hey, why are you so slow like a turtle?'' Li Yuri rolled her eyes as she put the books inside her bag and said, ''Then, leave already! Why do you have to wait for me?''Tang Min yawned and spoke lazily, ''Just hurry up!''

Li Yuri was speechless. 'Didn't I tell you to leave?' she thought.

- Outside, Street of Kingdom High School

Li Yuri was walking with Tang Min. ''Bro Min, how old do I look to you?'' she suddenly asked. ''1 year old.'' said Tang Min, teasingly. Li Yuri lightly punched Tang Min on his shoulder and scolded him, ''Hey! I'm asking seriously! Don't tease me!!'' Tang Min spoke, ''I think you're 17, aren't you?''

Li Yuri nodded and was going to say something when Tang Min spoke again, ''You're so small than me! I shall call you kiddo from now on!'' ''You!''

Tang Min ran away while Li Yuri chased him until they reached their homes.

- In Li Yuri's house

Li Yuri entered the house to see her mother sitting madly on the couch. She totally forgot about the wet bed sheets. She realized and gulped. She tried to escape from her mother but froze on her spot when Ji s.h.i.+ya spoke, ''Why was your bed sheets wet?'' She nearly slipped on the floor but she balanced herself. She turned around and bit her lips as she forced herself to say something, ''Mother... It wasn't me!'' Ji s.h.i.+ya squinted her eyes as she spoke, ''Then, who did it?''

Right at that moment, the door swung open revealing Li Yuran who was smiling brightly until he saw his mother. After he saw his sister as well, he let out a smirk. 'Now she'll get a great scolding from mother! What a great scene!' he thought.

Li Yuri squinted her eyes as she looked at Li Yuran who was smirking evilly. 'Wait and watch! I'll destroy your every plan!' Li Yuri thought and then turned to her mother. She innocently said, ''Mother, it wasn't me. I'm completely innocent!'' Then, she turned to Li Yuran and pointed at him, ''He did it!''

Li Yuran immediately defended himself, ''Mother, she was the one who did it! I'm the one who is completely innocent!'' Ji s.h.i.+ya pinched the s.p.a.ce between her eyebrows as she spoke, ''Who among you did it? Answer me!''

The room fell into dead silence until Li Yuri spoke confidently, ''I have proof! He was the one who did that! Let me show you!!'' She quickly took out her phone.

'What proof? When did she get it?' Li Yuran thought as his eyebrows were knitted together. The voice of Li Yuran was heard from her phone.

''It was my fault that the bed sheets got wet! She didn't do anything at all! It was all my fault, not even a single mistake of Yuri!'' Li Yuran's eyes widened. Li Yuri then spoke, ''Mother, I'm going upstairs. If you need anything, call me.''
