Han Yoohyun/Relationships

Han Yoojin
As Han Yoojin was the only one who had loved him when their parents find Han Yoohyun to be a stranger, and the one who had practically raised him after the death of their parents, Han Yoohyun is extremely protective of his older brother. He loves the pure love and affection his brother gives him, even to this day. Though, it is stated that he feels a little guilty that he continues to want more of the affection, when knowing that Han Yoojin could have lived a normal life if he had pushed Han Yoohyun away.

After he awakening as a S-class, he decided to establish his own guild despite the protests from other top guilds who tried to stop him. During the first timeline, due to his worries of the potential dangers his new position can bring for his brother, Han Yoohyun cut of his relationship with his older brother. He knew that when he is with him he may not be able to protect him. As a result, the brothers did not have a good relationship before Han Yoojin's regression, with Han Yoojin resenting his younger brother’s success and feeling abandoned. Despite this, Han Yoohyun eventually sacrificed himself to save his brother.

As a result of Han Yoohyun’s sacrifice and after Han Yoojin learned of the reasons behind his brother’s behaviour, the brothers’ relationship improved post-regression. Han Yoohyun is much more protective and possessive when it comes to his big brother. Other characters also have commented that he is milder when his brother is present.

Parents
During Han Yoohyun's childhood, the parents have quickly noticed the difference between them and Han Yoohyun. They noticed that they felt discomfort, foreboding and fear around him, a feeling as if Han Yoohyun wasn't their child but a complete stranger. Thus, this led their relationship to deteriorate, to the point that the parents have thought of abandoning him. Even after their deaths, Han Yoohyun remains indifferent, only grateful for the birth of his older brother.

Noah Luire
After seeing the bandages on Han Yoojin's hand, Han Yoohyun had at first assumed Noah purposely attacked his older brother, though later had been told that it had been an accident and that Han Yoojin simply was in-between a sibling fight. Still, Han Yoohyun appears to be rather calm when he asked Han Yoojin if Noah died, or attempted to run away.

Meeting Noah for the first time, Han Yoohyun held back in wanting to break him for hurting Han Yoojin. Their greetings left Han Yoohyun's impression of Noah's state weird, meaning if he's not normal, he is potentially dangerous. Additionally, when Noah had thought Han Yoohyun to be somewhat similar to Riette, thus asking Han Yoojin if he was okay, Han Yoohyun denies it, stating that Noah is 'a really weird person' and that he would never attack his hyung. Learning his past from Han Yoojin, Han Yoohyun to an extent understood the situation, though he remains impassive.

Additionally, after Noah stated he wished to be by Han Yoojin's side, Han Yoohyun's possessiveness did not accept the request.

Peace
Despite being the one who found him, both did not get along so well until Han Yoojin came to tame the beast. They are on a mutual relationship, finding themselves agreeing with each other to protect Han Yoojin.
