I feel you
Well , my take is Taizou repeatedly said he didn't get in contact with Ikuto.. If you think about it , it was a whole school year he barely came home. He's busy with his life. But I think Ikuto knew he was in love with a straight man and that path was leading to continual heartbreak, so he chose a path where he didn't have to see Taizou dating women at school. I may assume that my friend had left me behind and didn't care enough to know about my life if I was treated that way.
First, it isn't like I don't understand Ikuto's issues, I do. Second, I have tried to remember (confess to being too lazy to actually look) if Taizou says something. I think he does say something halfassed at one point about not bothering Ikuto, besides the drunken scene. But not something Ikuto would be likely to understand. Moreover it isn't made clear that they don't see each other at all, but it seemed more like Taizou just generally kept away and would be there on those occasions when Ikuto would be taking time off from studying like holidays.
If Taizou did say something even halfassed, he did try to communicate what he was doing to Ikuto, he just did a really bad job of it. Moreover you can't fault him for going out with women. He's not doing it to hurt Ikuto. I have to admit I wasn't clear on whether Taizou had actually moved away from home to live at college or not. If he had it would make it even more natural for him to be more away than he used to. Even if the college is close by.
But in the end, it still isn't the same thing as choosing to move away and ditching plans you made with your best friend without a word to them. Ikuto is only thinking of his own feelings in this matter without considering how Taizou will feel. If he cared so much about Taizou, even if he wants to get away, he'd want to do it in a way that Taizou could understand. How hard would it have been to say something- like sorry he'd really like to go to this college in Tokyo because of this department and would Taizou support him? In fact the story could have been much the same, with him going and Taizou missing him and chasing after him at the first chance.
Such a sensitive person. I worry for you when one day you have to deal with RL
"One day"?? I'm not alive? And perhaps you better not make any assumptions about me. From the sound of it you clearly assume I've had little experience of life. Tsk tsk. It is exactly because I have had experience with life that I understand the importance of being considerate of others. You, however, sound rather insensitive to others. What goes around comes around.
This may end all cute and happy because it's romantic fiction and all. But, idk, while I understand Ikuto's issues, to leave like that, to not apply to the same college after they'd been planning on going together for so long without a word of some sort of explanation is cruel to the other person. And then when the guy does show up in his new life, he is being rather a jerk to him. If we had no idea of how he felt and we weren't looking at this through a yaoi lens but at them as 2 best friends, though we might suspect, we'd still think that Ikuto wasn't being the nicest friend. Well guess who doesn't know.
That wasn't cute at all. That was rather mean and selfish. We sympathize with Ikuto not only because it is a story and we are shown his feelings clearly, but because we are reading this for the love. But if a BF suddenly did this to any of us, we 'd be like WTF???
