I truly loved how Tang Zhou loved Yan Dan and thereafter Ying Yuan 2.0 made me enjoy so much! Their love story is matured so its more about sacrifices they are willing to make for each other. Their love knows no boundaries esp when Yan Dan finally understood why the realms peace is much more important that anything else. Yan Dan became matured and Ying Yuan/Tang Zhou learned how to love and express himself. Its very relatable in our everyday life. Communication is the key to everything and one will sacrifice for the person he/she loves and also prioritise the world. This is how the world is supposed to be.
