REAL-701 Rin Asuka, the bright and lively sister I loved

I and my sister who live with two siblings who have no parents. My favorite sister, who has lived with me for a long time, got married. Congratulations, but my sister, who I meet once in a while after getting married, was active and energetic, but the situation has obviously changed like a lie. Isn’t the cause due to the man who is married? I understand that my guess is real …. REAL-701 Rin Asuka, the bright and lively sister I loved, changed her appearance after she got married to him.
