Can someone explain the valentine bonus? Like are we skipping to the future for a moment or...? I'm sorry I know this is a stupid question I'm just confused lol

The whole story of Here U Are is about YuYang telling their story, as how they met each other and all. The Valentines Special is a little forward than that, after they were already together as a couple.
Have you watched "How I met your mother"? Same thing, there is a great advantage in that kind of narrative, you can fast forward and back a lot, because the main point is to connect the dots little by little.
DJun also use some spoilers in the story to keep the viewers' attention and engage them in the story as it flows.

I really hope a new seme enters :/ I mean I wouldn't mind if Alex gets his act together but .. so far he's really let me down... I know the chance of that happening is slim to none , but it would be nice to see him with someone else ... I would even be okay with Alex seeing him with someone else.. getting jealous and gets his act together ... but damn how many chapters will I have to wait lol
Anyone else only ever read/watched this manga/anime? And not the one that started it all about his little brother? tbh I don't have any intensions on reading it ... this one fills my soul enough
There are a few parts in challengers (the one about senpais little bro) that are exclusively senpai and morinaga though, so even if you don't plan to read the whole thing, if you care about the characters I suggest you skim through and find those parts, imo it's worth it
Same , didn't even know it existed beforehand
