ok so

His older brother. This older brother decided to cut ties with his parents and family prior to Ren's story.






SPOILER: (3RD VOLUME OF SERIES)


And this is coz, like Ren, Saotome chose to be with his lover and pursue his medical career without the influence of his family. The brothers finally met at the end of the volume and they also introduced their lovers to each other. It was quite a ride, but I commend Jinguuji for being the catalyst for Saotome to eventually leave his toxic family.

thank you so much!!!
