Tbh I was #teamsensei for the first time....and it killed me ┗( T﹏T )┛...
There is also one new webtoon where the female lead falls in love with the second lead because the male lead originally in the story had a happy ending with the original female lead so the story right now is about the reincarnated girl and the second lead

Actually SPOILER.... he is very obsessed with the original FL...and during the engagement with our princess he actually develops feelings for her but makes her suffer a lit and doesnt tell her about his feelings and becomes really cold to her,makes her cry everytime...behaves like a child....very irritating tho
spoiler alert but

I wish the authors would stop making webtoons with second leads because 99% of all times they NEVER get the girl and always feel pain...always used for romantic development of the main leads...and I always fell for them HARD... (/TДT)/ I am in sPain where the “s” is sus
