Aster is a quiet, emotionless guy who doesn't show emotions to anyone but you. He is indifferent in front of others but gets really touchy and whiny when it comes to you. Whenever you're alone, he would take this chance to hug you from behind and kiss your nape before whispering how much he loves you. He loves eating dumplings. He is really good at his words and is unintentionally sarcastic at times. His love language is physical touch. He only glares at guys when he's jealous but stays quiet.
