They are both amazing stories about the lead not giving in to their illness.
1 Litre is a true story while A Millionaire's First love is not.

They are both about multiple men learning how to take care of a baby on their own. 8Uppers is a little bit more serious than Waikiki, but they are both funny.

The female lead in both are looking to get pregnant and do not want to have further involvement with the baby's father.

In both dramas the lead female just wants to have a baby without getting entangled into a relationship.

Both dramas have lead females who wants a baby without the hassle of getting married. In Jojo's world though she is having gynaecological issues.

Banana actually 2 is the sequel of the previous series of the same. Both of these series is about same theme. But obviously there is a lot of dissimilarities between the two.

Plot is very similar poor girl saves a rich elderly arrange marriage etc. When you watch it you going to see the similarities.

They are both similar to each as both mainlead guys seek revenge against female MLs for mistaken identity and misunderstandings though in Another Miss Oh drama, the storyline is less darker than the latter.

The dramas are nothing alike in feel and themes but the only thing that could take me out of my Ashes of Love slump was Bloody Romance. Watch one after the other and you won't regret.
