it's actually hard to say. like i don't really know what word or sentence is suitable to describe that feeling. but the thing is, there's a feeling of warm, safe, and comfortable. when you know that there's someone who will always be by your side. the worries you feel can be reduced a little because you know that someone will help you get through everything together, either it in joy or sorrow. it's such a lovely thing that has ever happened in your life.
