hello! so sorry for the late reply but thank you! and hm… gy jeno is kinda similar to bc jeno in terms of childishness, only gy jeno is 2x more hyper. he also has a much bigger obsession with jaemin so he’d very much adore how bc jaemin teaches and takes care of kids. bc jaemin would be kinda annoyed by gy jeno at first but it’s just a different jeno so ofc he’ll come to like him too. he’d scold gy jeno often for being naughty ane for worshipping him too much. also, since bc jaemin has two kids, gy jeno wouldn’t really know what to do but haewon and haeun would very quickly warm up to him and they’d urge him to play songs for them. gy jeno would probably teach haewon how to play piano/guitar/drums.
