Sweetness,bliss, comfortable, happiness, safe - those are the feelings that will appeared alongside the bitterness of love.

Bitterness, jealousy, pain, suspicion, envy - those are the feelings that will appeared alongside the sweetness of love.

What little confidence she has disappeared within a blink of an eye when it comes to him. However, she don't regret falling in love with him.
