OVI:
Ovi was led to believe by Arjun that he wanted to marry her, sent her gifts, and GOT ENGAGED to her. When the truth about him and Purvi came out, Arjun was extremely insensitive to her and did not even sincerely apologize for two-timing her.
Archana and Sulochana rubbed Arjun/Purvi's marriage in Ovi's place by coming to Deshmukh house all the time and standing up for them.
Also, Ovi used to drink because of her sorrows.
SOHAM:
Soham also thinks Gauri loved him because she was so nice to him. After finding out the truth, Soham is so hurt (which I understand) and drinking because of his grief too.
Similar to Ovi, Archana is also rubbing salt in Soham's wounds by reminding him that he has to do everything for the wedding
Differences between the two:
- Arjun actually agreed to marry Ovi, gave her hope, got ENGAGED to her, and pulled out at the last minute without any sympathy, consideration, and RESPECT for the girl he called his "best friend"
- Gauri never expressed any romantic interest in Soham and did not say anything to him that would lead him to believe she loves him (at least till now)
- Archana KNOWINGLY poured salt over Ovi's wounds because she knew all about Ovi/Arjun and was there for their engagement
- However, with Soham, Archana doesn't know anything about his feelings for Gauri and is hurting him UNINTENTIONALLY
- Biggest difference: Ovi was called psychotic, obsessive, selfish and other horrible names for drinking and being upset over what she suffered. Very few here showed any empathy for her.
- The same people who wished the worst upon Ovi, including death, are sympathizing with Soham (who is behaving similar to Ovi) and going "Poor Soham" "Poor Soham".
