similar to Beach Boys, Maharo Ekimae Banaichi is a comedic bromance related drama with a hint of love and slice-of-life.

Both are older dramas that are worth watching if you enjoy romance. The couples have magnetic appeal that carries the shows.

In both dramas a girl takes care of a guy who behaves like a puppy. They both live together

Both stories involves teenagers and they struggles to.... Have sex .both funny and with great actors

Both families have daughters with incurable diseases, and are there to support them hoping for the day a cure will come.

It's basically more or less the same plot - a pregnant woman ends up living with the family of her "supposed" deceased fiance when in reality she was only an acquaintance/friend of the person. and his fiance was someone else - both go through misunderstandings that lead them to live in another families home. Magic Ring is a train wreck, ring switch and amnesia that winds up putting her with the family. and in Chun Ja's Happy Events it's a boating storm that sinks, a ring switch and misunderstandings of both parents that lead the girl to live with them to escape her own reality. and in both dramas the lead girl falls in love with the deceased sons brother. lol - Magic Ring is a shorter Taiwanese drama while CJHE is a long daily drama (skipping is ok). But with both dramas there is a problem... Magic Ring is left uncomplete or at least not fully available for us... and CJHE is left unsubbed and hard to find (I found it only on Chinese site Soku). Since Magic Ring was made in 2004 I'd say it's safe to say that CJHE is a re-make. (but I can't be sure lol).

Both are about musical students making their way in the world and falling in love. Both are based off a Japanese anime/manga.

Main character abandons her fiance when she falls in love with one of her students.

In both, tthe husband/wife falls in love with the kind imposter while the real one tries to murder the imposter.

Both deal with the pure love story between the rich and poor who broke up because of their parents. They meet years later and still have feelings for each other.

Both series expand on one of the male roles who is in love with his older brother's girlfriend, but gets friendzoned.

Plot and main leads are very similar, except that in Devil Beside You the two leads are soon-to-be stepsiblings.

Main character had a crush on her childhood friend for the longest time. However, there was a girl he got involved with that he couldn't reject. Leading male's parent also abandoned him at a young age, but meet again years later.

In both, the main character had traveled through time and was forced to act as the lookalike imposter of the king from that period. He attempts to unify the kingdoms into one country.

They are pretty similar lessons, paths.
makes me write mores so I have to, sorry.
