That's my thought too. She deserves better but then that's the guy she loves. Maybe if there was another guy who it seemed like Rui could love but there's only Alex and she clearly doesn't care for him that way. I don't want her to end up like Shou from GE. What a kick in the face to Rui fans if that happens..

Actually wait. Who is that coworker guy who looks like Mori from Ouran? :V I don't remember him.

yep, even if she's too good for Natsuo, she really loves him. for now I highly doubt that there'll be another guy who can sweep Rui off of her feet. I quite like AL since it was shown that he really likes Rui but Rui can't like him back, only as a friend.
I have no clue about the new guy, perhaps he's a newly hired co-worker from her dad's restaurant.

here is the link for the raws....

I'm not really sure about all the details since I don't understand it aswell lol, but from what i got from seeing the raws is...
...spoilers...
Rui will avoid Natsuo for sometime. Natsuo is always waiting for Rui at her dad's resto, then one day when it was raining really hard she saw Natsuo waiting for her outside drenched in rain (lol this made me fall for him), Natsuo passed out and got sick, they made up. Hina found out about their relationship. We got introduced to Natsuo's Drama Club, the main actress seems to like Natsuo (this I'm not sure if she likes Natsuo but I think she's with a girl aswell). Hina met a new guy from her workplace and introduced the guy to her family, Natsuo was a bit shocked but he still loves Rui. Recent chapters is that the guy Hina is dating seems to be a stalker and obsessed with her. there are moments where Natsuo is still blushing because of Hina and Hina still likes Natsuo and dated the guy to show off to Natsuo.
I just saw the Raws - up to Chapter 180. Omg Sensei, please I hope you'll end this manga already, I thought this will have the same pattern or atleast almost the same as GE, BUT NOOOOO. This is just getting absurd as chapters passes by.
I just want a Rui x Natsuo ending.
Even if Rui doesn't deserve a piece of shit guy like Natsuo -- but since Rui really loves Natsuo, what the heck. ╮( ̄▽ ̄)╭(╯°Д °)╯╧╧
