In my opinion, Youngji's part is what Youngji felt, and Kyungsoo's part is the message that Youngji wants to convey. Male role, Kyungsoo, is a short man. However, he has high self-esteem and loves her the way he is, so you can find that he is more concerned about the small scars on her fingers than her tall height.
Exo is still under Sm as a group because sm owns exo name but Kyungsoo established his own company with his manager so he is under his own company now, but for exo activities he will work with sm it will be like a collab of two companies for work wise , something like that. Because kyungsoo doesn't have any contract with that company anymore
Kyungsoo / D.O. did not renew his exclusive contract under SM. He is the only one who did not renew. But he is still with EXO. He has no exclusive solo and group contract but he is still with EXO.
