Please Come into My Heart

Same main leads and they both hold elements of time travel as well as overall being comedic and interesting. The chemistry between the leads in strong in both of these vertical dramas if you liked one the other is DEFINITELY worth a watch.

Both hold time travel into ancient times elements and are comedic. Main couples have great chemistry and friendships while helping one another.

Same leads: See Liu Nian and He Cong Rui together again, and you can expect amazing chemistry between the two.
Liu Nian in both plays a woman who transmigrates into another world (historical for Please come into my Heart and modern for Lingering in Mind) and wins the heart of a high-ranking / rich man (ML is the emperor in PCIMH and he's a rich CEO in LIM). While he comes off cold at first, he's actually a huge softie with a sad/traumatic back story. He slowly opens up as his personality is balanced out with Liu Nian's usually very bubbly and charismatic characters, and his protective, affectionate (and adorably jealous) sides of him come out. Both are very entertaining watches!
