i would love (and thats a given) his history with tatsumi and his identity crisis, more than anything because they have what he seeks to find: being happy and open with who he is. It was no coincidence that it was mentioned that his personality is similar to Minato's (coincidentally, he asked him to speak) I think that through Shizuma he is projecting a certain admiration and not love.
There isn't much progress with Tatsumi, but the little that has been shown so far is a very key moment for them as a future couple because there have always been moments in which the director finds himself emotionally open due to events, i can't wait to see his development, especially because it will imply individual changes for both of them and then as a couple (like Shizuma and Minato) and I also hope for a certain friendship between the director and Minato, since they will find themselves in very good company due to being so similar.
