It is a hard lesson. If it is troubling you, perhaps you should discuss it with your friends. That helped me.

[Though, how much it helped is debatable. Her friends did come to her rescue, but they all died again anyway. Rika is keeping a calm expression, but the memories she refers to involve more suffering than a normal girl could bear.]

Friends can be as powerful or as useless as you allow them to be. Happiness, too, only has as much value as you actively cherish.
