both were in a park sharing as a couple, although their relationship was not public since Heeseung did not want to tell anyone that they were together and you agreed to hide their relationship. They had been together for 3 years in secret, at first you didn't mind having a secret relationship but over time you began to see that there were many limitations such as holding hands, hugging and also not kissing in public. And lately you feel Heeseung colder or more serious with you. He looks at you and speaks first

"I want our relationship to be open" he says in a soft but serious tone at the same time
