agree!! i prefer Daiki in the past than now.
Daiki in the past must have been the type who does anything that he wants. Similar to a child but far from that. We can all see how he does things 'his' way lol. Like if he wants a kiss from Sawato, he gets it. Or if he feels like watching him taking he bath, he'll do so and no one can stop him. But it's evident that he has a sweet nature in him. Present Daiki on the other hand isn't anything different. It only seems to me that he is now very vocal with his feelings (saying I Love You's etc) and somehow more matured. I spoiled myself a while ago and 'read' the raws. I think Daiki really has changed after the accident. But I won't spoil you so just take your time XD It gets exciting this way.
I feel for Sawato. Both parents tragically killed, left with a special needs brother to care for and now at a young age has taken on the burden of the village. There's a lot on his shoulders, and then he's wooed and finally gives in to Daiki and then "loses" him, too. Sure, he could be a little more understanding but it's hard to completely fault him for being angry at yet another hard turn of fate in his short life.
I don't understand why you guys hate Sawato but every single one of this characters has all their reasons. This is why we have flashbacks, because the author wants us to understand why things turned out to be like that. Indeed Sawato is one huge tsundere, like he doesn't know how to express his feelings. He makes a rather unpleasant face and actions whenever he's with Daiki- BUT OBVIOUSLY he begins to start liking him back. Why else would he get mad when he found out that Daiki had taken a liking to his grandmother when she was still young? I think Sawato is a lovely character. He just needs to be understood. Don't take things superficially and try to understand his situation. Yeah Daiki's all sweet and nice but the story doesn't end there. If you just try to keep on following this story you might get why it takes too long for Sawato to accept and fully understand his feelings and why the PRESENT Sawato yearns for the old Daiki - which we all see right here.
