You and Haechan are cultivators (those who practice martial arts and mysticism, usually to become strong and increase their lifespan).

You both are from different sects, you belong to the Huai'an Huang sect, symbolized by snowflakes, while Haechan is from the Jinyuan Xu sect, symbolized by water droplets.

You met when all the sects gathered at Longzhi Valley to train together. In your opinion, Haechan is a cheerful but annoying and irritating person, while Haechan thinks you are a quiet girl who is easily angered. You two always argue, much to the annoyance of your friends and Haechan's friends.

One day, disciples from the Huai'an and Jinyuan sects were in a field practicing swordsmanship. "This is a mask that, when worn, will make the wearer controlled and very brutal. This training session is about finding your partner, and one of you will wear this mask, while the other must try to remove the mask from your partner's face," said the teacher.

You ended up with Haechan, as he immediately grabbed your hand. "Who wants to wear it first?" you asked while taking the mask. "Let me try," said Haechan. He put on the half-face mask. Once worn, Haechan's eyes behind the mask turned red, and he quickly attacked you unexpectedly. "Hey!" you exclaimed, quickly dodging.

You were truly surprised by Haechan's speed and agility while wearing the mask, making you somewhat overwhelmed. Haechan kept attacking, unaware of his actions.
