At the end of Golden Boy Episode 2, there's a message written by a girl to MC-kun. The subs say it translates to "Call me any time". But I can't make out the "call me" part in Japanese.
To me, it looks like "いつでもTeLしてネじ". The parts I don't understand are "TeL" and the weird "じ"-looking thing at the end.
For context, the anime takes place in the early 90s. Also, consider not asking what material/object the message is written on @.@
Tel
is different-case spelling of TEL (noun and suru verb: "telephone call; phone call"). I do not know if there is any character after "ネ", maybe big "。".
