What constellations are Lin Lei and Song Yuhang?

Lin is a Gemini, Song Yuhang is unknown.

It is mentioned in the novel that Lin Lei's birthday is June 18, so Lin Lei's constellation is Gemini, but there is no information about Song Yuhang's constellation in the article, so the current constellation is unknown.

These two people are the characters in the novel My Dear Miss Forensic Medicine. A talented young forensic scholar named Lin Lei and an introverted criminal investigation captain named Song Yuhang have repeatedly solved strange cases. They had an intersection because of an old case that spanned two generations. After fighting and dying again and again, two people who were originally tit for tat gradually entered each other's hearts. The novel is very good and worth recommending.
