Sudden time travel
Calm and happy-go-lucky
Gentle and peaceful
The strongest soul is the loneliest helplessness
The stronger a person is, the easier it is for others to ignore him and protect him
The weaker the person, the easier it is for others to ignore and watch out for
Tender smile and chivalrous heart
Who laughs, who cries, and who is numb in grudges
After the ordeal, who lives and who dies and who is the winner?
