I'm not in a relationship, but yes, admitting jealousy is very hard to say, because in my instance, I feel ashamed for it or I'm just in denial. Communication will be far easier for the two if they could be honest with each other, but they're not being honest, so it'll need some adjustements first. Honestly, I think admitting to something is already hard enough as it is..
Yeah plus, Sayama should be able to tell he is jealous as well. It just doesn't make sense how the new guy is almost like a second male lead.
The seme is not toxic, he's just feeling jealous that his lover is getting closer to someone else and this is a normal feeling, I'm sure every couple has experienced this, but if they want to fix their relationship then that's where communication comes in! And communication is not such an easy thing afterall I'm sure not many people would like to admit that they feel jealous ( at least not me )
