Arent they all stalker lmao
Mitsu stalker is Hachi and Tate is Hachi stalker. In chapter 9 there are envelope of stuff about Hachi in Tate closet. Idk how exactly Mitsu is a stalker since Tate clearly goes to him and Tate used him to get close to Hachi. I think Mitsu is just very possessive and obsessive of Tate because of his feelings for Tate rather outright being Tate's stalker.
Im gonna say mitsu is tate's stalker cz he know what tate gonna wears the part when they meet on the train. And i alr read chapter 9 but i got a hunch theres more in the next chapter. They just stalking each other atp like the title says abt this manga afterall.
Judging from the author's other works. I guess the stalker gonna be the winner wake me up when mitsu get his own story. I can't with this.
