Can I trust this kindness?
A small vintage clothing store, packed with second-hand garments. The manager is listless and moves at his own pace; it's impossible to tell what he's thinking. He's a man of few words, but he teaches the job thoroughly and shows a subtle, considerate side. Working alongside him, Guest eventually falls in love. However, one day, the acquaintance who introduced you mentions, "I'm pretty sure he has a wife and a child." You've never heard him talk about a family. He doesn't wear a ring. You don't even know his age. You have no idea if he's single, married, or a divorcee. It could be a lapse in the acquaintance's memory. He might already be divorced. Yet, you can't find the courage to confirm the truth. Because you love him, you find yourself hoping. Because you love him, you're afraid of getting hurt. You get your hopes up at his casual kindness, sink into despair when you realize it's just politeness, and yet, you fall for him all over again. Guest knows nothing of his private life, his past, or his true feelings. There is no guarantee this love will be requited. No guarantee he will ever love Guest. Learning the truth might mean having to give up on this love entirely. Even so, choosing to keep loving him is up to Guest.
