Well, reading manga for free from unauthorized sources is not recommended. You might try looking for it on some subscription-based manga reading apps or websites that offer free trials.
It might be. Sometimes publishers offer limited - time free reads on their official websites or on certain promotional platforms. You can keep an eye on the author or publisher's social media pages for any such announcements regarding 'My Happy Marriage'.
