Jdrama - "Jitenshaya-san no Takahashi-kun". Small serial with 8 episodes only. They got together at episode 3. There are two small fight/misunderstanding between them after that. No breakup.
ML showed his interest in FL from the very beginning while FL fell for the SML at first. But, over the time she knew that its not possible for them and ML also started to capturing her heart gradually. She confessed her feelings at Episode 8. There was one episode of tension between them (Fl even thought to breakup) because of her inferiority complexity and family situation, but they didn't breakup at last and proudly declared her relationship in front of her parents (last episode).
Second Leads also got together at Episode 8. SML and SFL were friend from the beginning, but SML liked her secretly. When SML revealed his intention, SFL rejected the idea and wanted to keep going as a friend only. But, soon she discovered her feelings and got together at episode 8 (In later part, there was some tension because of her ex coming back, but that was passable).
I read that they had an intense argument and emotional break around episode 9 leading to ML’s jealousy and mistrust…
FL asked for a breakup because of the threat from her toxic ex, which might implicate ML. FL avoided ML sometimes, but, imo, ML didn’t agree to a breakup; instead, he figured out the reason and got back together in the same episode.
They got together around Episode 12/13, got married in Ep 15. There is a rumor of their separation spread around Ep 21/22, but that was the part of their planning.
Hey Drama Lover! Can you spoil me a little bit... I heard that there is a love triangle with the kinda annoying…
They get together at the end of the episode 7. I didn't find it annoying as FL always treated the SML as a friend and a co-worker. SML also didn't show any obsessive behavior after FL rejected her. Both ML and SML moved to FL house, so yes, SML also have a good amount of screen time.
From the comment section it appears that they got together around episode 10, broke up episode 11 and got back…
I have a little bit different opinion about this drama. Drama started with their reunion after 8 years of breakup. Soon they find themselves attracted to each other again but FL was still in hesitation due to the past trauma. They kissed passionately at the end of the episode 10 but another incident shook the FL up and stopped them to make their relationship official. FL wanted to keep the distance from ML, but ML, without confronting her directly, kept himself near to FL. I don't count this as breakup, because they didn't confirm their make up at the first place and ML never distanced himself from the FL. Finally, they made up officially in episode 20 and didn't have any single misunderstanding or breakup after that (I found this part very good from the romantic pov, specially they shared every details with each other immediately).
