Yes, I forget how long it's been, like 5 years maybe, but it's after He Tian suddenly disappeared (to work hard and make his own money so he can care for Mo), so there's still some slight tension after he suddenly left Mo without saying a word. So they're like young adults now
When was this? What chapter?
Uhhh I don't think it shows the actual moment He Tian leaves and Mo can't contact him, but it looks like chapter 454 might be the moment He Tian returns. I know it's hinted in wayyyy earlier chapters that He Tian disappears for awhile, but the story does it in like flash-forward moments, if that makes sense. I'll try to find the earlier chapters
Okay I reread it, and yes there isn't a specific chapter that shows when He Tian leaves, but these chapters are kinda around when he first returns, 224, 271, 313, 378, and 412 (they're Christmas specials, which is why they're so spread out). I forget if it's actually mentioned in a chapter, but what I've found from my own research is He Tian might've been gone for at least three years, but I've also seen others say he's been gone much longer due to him starting his own business. Hope this helps!!
It's been a while since I read the last chapter but ARe they already adult??
