A piece of cake, bff. You ask to the right person who understands Black Shadow's core.
Foremost, try to match with his quirky even your 'asbun' skill will be beneficial to deepen your love. Be prepared as wholeheartedly with his abruptly appearance since it gonna snap your dugeun-dugeun. Then, try to sneak peak your vvibu friends' discourse so you can bring bunch of topics to your Eunseok. If you ask me to find his clone, well I'm rooting on you instead. HAHAHAHAHA.
