What a ride — the tricky thing is that 'Mate' isn’t one single book or comic, it’s a title used for lots of different works (novels, romance/webnovels, and even manga), so where you can read it for free depends on which 'Mate' you mean. For a webnovel titled 'MATE' (the werewolf/fantasy type story), the creator has a listing on Webnovel where many chapters are available to read on the platform (some chapters may be free while others use in-app coins or are behind paywalls). If you’re after a completely free and legal route, check your local library apps first — Libby (OverDrive) and services like hoopla often let you borrow e-books, audiobooks, comics and sometimes webnovels without paying per title; all you need is a library card and the titles will vary by library. That’s a great way to read legitimately and avoid sketchy scan sites. Finally, if the 'Mate' you want is a manga/BL title, some series get legal English releases on platforms like Manga Plus or on publishers’ sites/apps, but others only appear on fan-scan sites (which I don’t recommend). I found a fan-hosted listing for 'Mate Ga Dekinai Wataru-Kun' on an aggregator, which suggests it’s circulating online but not necessarily via an official publisher — that’s the kind of thing I’d double-check against legal platforms first. Bottom line: look up the exact 'Mate' by author, then check official stores/publisher pages, Webnovel or Wattpad (if it’s an indie serial), and your library apps like Libby or hoopla — I usually find what I want that way and feel better supporting creators, too.
