Kouga is my best friend.

He cleaned the room thoroughly.

This building is made of a steel frame structure.

When reading Kambun, it is important to check the position of the 'kaeriten'.

He developed new software to systematize information.

He flattered me into participating in his plan.

He is a master of iron fan technique.

A new branch of the supermarket opened near my house.

His attitude is without affectation, very natural.

From his point of view, the problem looks completely different.
