Well passion is similar to this, the mc likes 2nd ml, but when he joins the military I think, he meets the guy named ilay, he doesn't like ilay cause his type is the 2nd ml. It's a very long,ongoing bl but it's interesting story. I think you will like it
Ohh do you have more recs? Like MC switches love interest? Like the one you mentioned (Passion) thankssss (⌒▽⌒)
Dear door and nerd project, backlight, hope it helped

If anybody has any recommendations that is similar to this. Like the whole ml into someone else and the mc is in love with them. Send them my way. These be interesting
