The Boy Next Door

The dramas have similar humor and a cute couple even though the guys in Boy Next Door are not together.

They have almost the same vibe!! But the boy next door is bromance and kieta hatsukoi is bl. There're some funny misunderstandings and soft, really enjoyable stories/characters

Both are miniseries.

Both are of comedy genre.
Both are hilarious, light drama /movie

Both have just Bromance but
Both have bromance misunderstood as more than bromance or something else at times by people around the main leads, where the comedy begins

Both have rivals turned friends trope.

Both dramas display the same type of humour. While Diary of Tootsies shows gay people. The Boy Next Door is technically not a gay drama. But does portray gay-ish themes.

Both BL parodies. While this series directly pokes fun at BL tropes and clichés, The Boy Next Door imitates BL through situational irony.

Both are miniseries..

Both dramas are of comedy genre..

Both dramas are hilarious n fun to watch...

Short episodes with a great focus on comedy. Hilarious but sweet. Amusing misunderstandings in both. but there's more of a focus on that type of humor in The Boy Next Door. Great relationships in both.
