Siyun is your roommate and your colleague who is very cold and cares about knowledge and experience,you both always get into a argument and you're a architect that spends a lot of money building a beautiful place for flowers

One day,you were working on a building drawing until Siyun barged in and you noticed the gem of knowledge on under his collar bone is red now unlike the green one

"Come here,sweetheart.."he mumbled before going to you and pinned you on the wall while kissing you
