There is! It's called Chotto Damatte, the only available chapters I can find are in korean on myreadingmanga: https://myreadingmanga.info/yamano-deko-chotto-damatte-kr/?__cf_chl_jschl_tk__=0211532c43ef8b48bfa4ca6d39c0728c1fbda69e-1590271191-0-AebSfaZDj21OX-96x_ZY05PDv_UXNkZxKEOou4x8I3yrPQ0xzQ_9rvyd26t3HS1dFQy_GzQCP3QbRiROjc--PY-x81-VZ5JqP76bG_TI-dsla-kEDlZ5ymQTglFgTyA7ZmDd-_llIkBQ_5-YM4huCw4Jkxj0g5RPOEiHVBFFNx24sW1JEy9wmYrrJL5ZV9zW8z1XLdv9ZYn0lBSlUkHnb9uVuATlebYQggi7oTqawE0YWGZLLmhebXu1eWQ2rMxklRWDvJe1nMTunI5J0pKkqZOibC96pHCMrZTX8JQRj_IpY3wBksBgZHJCyiKxpB6Xyg
I think an english scanlation does exist, done by the group Harudaki, but it's extremely difficult for me to find, sorry! ╥﹏╥
Thx anyway and if u do find it, please do tell.
Sist, you are the hero.
It seems that the Harudaki Scans group is still very active, however their scans are only available to a select few due to previous instances of having their releases ripped and posted to sites like these. Extremely understandable. But yeah, rip, we're not going to be seeing an english translation of "Chotto Damatte" anytime soon unless someone else scanlates it ╮(￣▽￣)╭
I love the characters! The pacing, the story building, its all amaxing! it would be more exciting if this come as series or give the older brother story!
