Inspiring movies about music. While Swing Girls is more comedic and focus on music band, Have a Song on Your Lips is more serious and focus on choir group. But both are relaxing to watch, with beautiful sceneries.

Both dramas are based upon the same source material.

Although they both have different type of story but if you like the chemistry between the male lead and female lead then dont look further .. Legend of fuyao is one of the best chesmistry ever between both ml & fl lead.. The UI is not as advance as now but i assure you will like their relationship.. Give it a try till 20episodes upwards and you will be hooked

Friends to Lover trope , University life , campus life , Long time friends , childhood friends , Roommates relationship , Cheerful male lead....
I find most of these very similar...
Mainly the male lead and female lead friendship...
Not the whole storyline is similar but i find the character development and the initial relationship between the leads slightly similar..

This is a spin-off of cutie pie with YiKhondiao as the main cp and focuses on their story and journey as a couple.

Black comedy with "assassin" concepts, with similar use of action and rock music for action scenes. Both also, despite a focus on comedy, have emotional scenes.

INSTANTLY reminded me of it
both university, youth, spring kdramas
popular and loud/outgoing ml who has problems going on who instantly falls for and follows around the unpopular / quiet fl
the personalities are sooo similar
2nd lead (he’s not rlly a second lead in AADSIG but yk) both are cold at first, the 2nd lead in SOY reminds me of sobin’s childhood crush
3 main characters 1 girl 2 boys
their NAMES are even similar like
kim bom, kim sobin
sa gye, yeo jun (2 syllable names)

Both shows are so cute, the love that blossom's between both of these couples is a giggling, giddy kind of first love .Such cuties.
