I think this will get super toxic real soon. Seme will fall in love with uke but uke likes the professor. Seme will try his best to stay with uke knowing his relationship with the professor. Then seme will get tired and leave then uke will realise. Oh yeah and that professor will fall in love with him but by that time uke is already in love with the seme. The end!
Maybe the blonde will turn out a little weird but I still don't support yahwi. Jooin my boy, Yahwi sunbae is toxic and you need to stay the f*** away from him. You deserve better. Just dump both of them.
