Dramas without annoying love triangles

Romance is only a subplot, but there is enough romance in it, ML liked other girl for a short time but it was only for 1-2 episodes

I liked everything about it, I put it on hold for so long because it has 133 episodes (30 min each), but it's worth a watch, probably the best FL I watched in kdrama's, there is no love triangle, only a minor breakup  around episode 115 but they were still in contact so it's not annoying, you have to prepare yourself for a emotional rollercoaster if you decide to watch this, ML is miserable from start to almost end, but FL never left his side and always stood beside him that's the best thing about this drama.

Romance subplot

This is one of the few long drama's I was able to complete, there are 4-5 couples, none of them have love triangle or break up.

Oldest brother- no love triangle, started dating around episode 13, married around 35

2nd brother- his ex is trying to get back together with him, it will last upto ep 11-12, started dating FL around ep13, minor breakup around ep 38, get back together around ep41 and get married

Youngest couple- most dramatic, breakup around episode 25 and get back together in last episode, there is also a other guy around FL, she never liked him but spent too much time with him, but nevertheless he has no chance, but youngest couple was my fav. Till episode 20 before breakup so I skipped all there scenes especially FL and other guy.

Romance subplot

There are four couples, 3 end up together in the end, one one who end up alone has a love triangle, I hated her character (xiao yu) so much so I skipped all her scenes, all other couple stories are good 

Although there is no love triangle as both lead likes each other from childhood, there is a very annoying SML who likes her and FL spend too much time with him, it was annoying, he is the reason I deducted .5 from the rating.

This one was so wierd but I liked it. It's only 1 hr. Long, ending was incomplete so there is chance of season 2

Romance subplot

Slow burn, there is a school time friend who like FL bit has no chance, they only have few scenes, he is not clingy and will be paired with SFL later.
