I dont think so? They're still high schoolers so chan liking sami can pass off as him exploring and discovering his sexuality further
gender is fluid so i don't think it's bad that he can be both into men or women or to anyone at all.
Only crazy obsessed fujoshis would think this is bad writing, but then again theres no way theyd read this since its not yaoi lol
I think some will still read this then maybe some will also think bad about him having a crush on sami since their expectation about him and his friends becoming together will be destroyed.

Would it be a bad writing decision to turn chan into a bisexual? I’m curious because I want to hear how others think and by no means do I want to offend anybody by asking this!
