what are the odds she SOMEHOW doesnt break up with him and it causes issues later? Haha surely not..right..?
Honestly, if that doesn't happen, it would be a waste. Why include him in the series at all, and even keep them "dating" if it's not going to serve some narrative purpose? I'm assuming his inclusion is about providing her an opportunity to showcase her growth when it comes to peer pressure and conforming. She'll have to make a clear decision. She's definitely down bad for our girl but we already knew that. The issue is doing this stuff publicly around her peers.
On the other hand he kinda already did by being part of the reason MC was reluctant to interact with Yarai at first so could go either way
