Thank you very much for your kind words! I only realized it after you mentioned it, honestly ^^” But, I think it’s because of the heaviness of the phrase itself, what it stands for and the commitment it comes with it. Since it was really just the start of their relationship, I think Seokjin couldn’t bring himself to say those words because he wouldn’t want to get too attached. I’ve been thinking of writing a bonus chapter for that book!
