It's amazing how talking to your parents, friends, siblings about how you feel doesn't help, but it's amazing that a character like Miku reaches the bottom of your heart in such a warm and comforting way just by approaching her and staying silent while she tells you with certainty what you need to hear to heal. I don't feel the same when a person tells me that but Miku, she is pure magic. I was crying when she found my box of buried feelings and memories I had to pause the video and say to myself "Is this real?"....I'm saved by her.... again :')
NOW I UNDERSTAND! cause if you get this card in the gacha/spark it is actually a reference to this cause the voiceline being “why did you shut the lid..”
