Its not that they are late but the real shiyeon doesn't accept their concern and keep distancing himself to other mean while the current shiyeon do nothing and let the members do what they want its like accepting them also. Well can't blame the both side cause the real shiyeon have so many trauma and hurt at the same time and the members are also hurt when shiyeon push them away. But still poor shiyeon may he be well and peaceful
It's actually really sad that the Real Sihyeon suffered so much and never got to know how much the other members cared about him and never got a chance to prove himself. It's also pretty sad that the members are showing him with affection now, but it's too late and they're just being nice to a stranger and apparently like him more than the Real Sihyeon.
