With every episode, "My Journey to You" reminds me of Joy of Life because of the mind games between the characters. Both are also of wuxia genre (non-traditional) but have wonderful plot lines. Albeit, Joy of Life has attempted assassinations on male lead while the main lead in My Journey To You is the assassinator. Both are amazing dramas to watch and keep your brain eager for the next clue and episodes.

When We Were Young and Never Grow Old are very similar s they are set in the 90s if I recall correctly.
They focus on friendship and family bonds, more specifically the former.

Three sisters fight for royalty, power and pride.
Eldest sister wanted the Queen's throne.
Second eldest wanted someone that loves the main female lead.

Similar characters: Slow learner female character and a very smart and idolized male character.
Both female main characters chases after the smart guy who she is adamant on becoming his girlfriend no matter what. Male character doesn't care or just lets her do whatever.
