I reincarnated as the hero's childhood friend who was the losing love interest, so I changed jobs to

I read somewhere that Lucas is gonna fall for the OGFL again. So I hope the FL ends up with Arnold. 

It reminded me a little of "This Time I Will Definitely Be Happy". What with the whole ditching the hero who the MC knew and loved since childhood because he'll go on a journey and forget her and fall for someone. Also, the MC in TTIWDBH remembered her past lives where she was unhappy because she was always waiting for the hero to come back to her. But in 'Definitely Be Happy' the execution is better and the characters feel more fleshed out. Even the world-building is more comprehensive. 

Thanks for the spoilers! Truth be told, a part of me didn't mind which guy ended up with MC (since current Lucas is considered/treated differently with OGLucas), a shame he didn't find his happy ending. I certainly wouldn't have mind the OGleads to end up together reading the dream spoilers and all. Kinda weird we had a drought of spoilers since the novel hasn't updated (last I checked) and the manga according to the latest translator had been watermarked in its raw source. 

Someone please spoiler it. I need it. Since you guy say the hero have vision of heroine then he gonna end up with the her...? Not our mc?? It made me more confused. Who is actually the ml?? somehow half my brain I didn't want he end with the heroine and half my brain didn't want he end up with our mc.

Someone please spoil a bit  

The names Arnold~
He's an elf?

Japanese loser protagonist syndrome. Nobody in the country demands anything, or negotiates understanding their strengths. It's what made me lose interest in the novel. As far as I can recall about the heroine her last appearance was helping out Laura with her experiments
