I cannot understand why Eugen will like you... ...

Although in many occasions, her actions is hardly understandable.

So... Sorry

Although we may argue a lot, but I am still her elder sister

I must admit that when she is with you, she has changed a lot. Her smile has become more natural than before.

In reality, I am happy to see her acting this way...

I hope she can forever stay the same

You are really asking for a beating, isn't it?
