@Bainhardt Even without the t/n I knew how amazing the original pun was. It's a shame there isn't a single way to match that amazing-ness in English. The best I can come up with is "Fistelescope".
This could also go either way. Based on Tanaka's reaction ueno could be thinking that tanaka takes relationships seriously and thought of it as a prank or it could mean that he doesnt like ueno and shouldn't do that. But of course her plan backfired tremendously.
