I thinks it's more like others will notice Miike and see how adorable he is, that's why Hifumi is jealous.
In my opinion it's ok to be a LITTLE jealous in a relationship, some find it cute when their partner is worried. Jealousy is in humans' nature, it's a normal emotion. It's not ok to be extreme in anything, like when jealousy becomes obsession, THAT is toxic

I wouldve given it full stars but theres something i wanna know. Is it a translation error when hifumi says that miika shouldnt put his hair up even if it makes him more confident? Because although this was adorable, thaaatss pretty toxic behaviour
