I haven't read this so I only remember the synopsis. I think MC is a emperor and ML is a prince regent, in their past life.MC then gets reincarnated (i guess? ) becomes an idol or smth similar and miss how prince regent always help/pamper(?) him. Turns out ML also get reincarnated and become someone with high position in entertainment circle. At the end of the synopsis, MC says something like 'You finally come! Zhen miss you so much' or smth alike. That's all that I can remember. Seems i haven't add it to my reading list and now i can't find it.
