I don't think it is rushed. He's kept his feelings quiet for 5 years. All that stuff we saw about their relationship was a flashback. So all that's really happened in the present time is the conversation. What did you want them to do?
Okay, but to me, personally, it felt like the manga was set for more flashback. They skipped over him running away after they did it and then those five years in between. I know they weren't going to go over all of that in the manga since that would take way too much time to cover, but it still feels like they were going to put some thing in there, some sort of transition, which going back to and reading the manga again, there was no allusion whatsoever to the content that started the next chapter. Usually they do that right? Leave some sort of cliffhanger at the end of the third chapter that leads into the start of the next chapter, correct? Now I may be wrong, I'm not claiming to know the mangaka's mind, but it still felt rushed, from the end of the third chapter to the fourth chapter.
Considering this story isn't from Tora's pov I think it makes sense to skip it. He doesn't know what Tora did since the night he left him and the gang.
They've never talked about it.
Maybe later we will see it from Tora's pov?
You can actually kind of guess it why Tetsuya called him after 5 years, it seemed like his parents passed away, that's why, looking at the cover of the chapter.
Tora in the meanwhile was trying to avoid Tetsuya and his feelings for him for those 5 years, though after Tetsuya called him and said "come", all his efforts were gone, haha
Hopefully this story also gets 2 volumes like that of Ryou, so we get more aspects of their feelings and thougths covered! :)
Mmm...I'm happy but it still feels like they rushed the plot to get to the sex. Don'y get me wrong I'm all for the sex (hehe), but still the plot had a nice vibe going and then update: Bam! Have sex with me. Too fast! Way too fast!
