thoughts about the ending:

firstly women who stayed alone:
- Park Sejeong: i'm sad she didn't got any attention and didn't go to paradise, i kinda hoped she will go there with Jinyoung at the last trip, even as friends. it can be true it's because of her beauty which doesn't exactly fit korean standards. she tried to talk with boys but her approach might have been not enough. tho she suprised me, cause at the beginning i thought she is more mean (??), but she was really nice and supportive
- Lee Minsu: same issue as in s1, she came to late, when people already knew each other (Jinyoung came relatively early in comparision to here). as she said she had to choose one person, but unfortunately she focused on Jinyoung who already had his fanclub. i have mixed feelings about her behavior - in one way people say it was wrong for ex. when she went to Nadine and Jinyoung or when she still chose him to go to paradise, even when he very clearly said he wants to go with another person; i understand people can think she was behaving rude, but i don't think it was that bad, she just have tried to pursue the person she was into, furthermore she didn't have time to choose another person (while also she didn't really knew the dynamics so well)
- Lee Nadine: to start, i didn't really liked her nor was a part of her fanclub (on the contrary i felt some ofher fans were really rude, especially on twitter or instagram). tho still i think she behaved well in her situaton, trying to pursue Jinyoung, she did good job even if nobody supported her openly in the show (cause other members were mostly focused on Jinyoung-Seulki dynamics). i think main reasons why Jinyoung didn't choose her: she wasn't his type based on the looks, he felt too comfortable around her (and as he told Minsu he don't like it with his partner), she was too young and unsettled and also she considered relationship as something she need to put a lot of work into (while Jinyoung wanted more space, according to what he said)

okay, now time to the rest:
- Soe&Sejun: i think they will probably stay as friends. it would've been weird for Soe to go alone and leave Sejun so she might felt some pressure over this. they seem very comfortable around each other tho and Sejun is very into her, tho i still think that he appears to Soe more like a best friend (it very reminds me of Yeawon&Junsik from s1, they have also stayed as friends)
- Seoeun&Yoongjae + Hanbin: they have amazing relationship. maried couple. no doubts. i hope and think they will stay together, they are both similar, chill; about Hanbin, i'm his biggest fan, he just behaved so well, acknowledging his feelings while also not putting pressure over Seoeun, i hope he will find someone!

now for the biggest melodrama stars of this season...:
(about Dongwoo, i don't think there's a lot to say. we know how she feel about him)
firstly i want to say i was a big Seulki&Jinyoung shipper. tho in last episodes it have changed, and i liked Seulki's choice a lot. it was very mature of her. she knew that she felt something for Jinyoung, but also she might have realise that their relationship could not last. i think they had more of physical intimacy between each other and while the 8/9 days was full of chemistry, later it could've changed. she didn't feel secure around him, he seemed hard to read. and while all the times she was feeling bad, Jongwoo was there to comfort her.
personally i think that initially after her trip to paradise with Jongwoo, she thought more about choosing Jinyoung at the end. what changed her mind was her talk with Jinyoung. she was giving hints for him that she wants him more, that she likes his personality. while Jinyoung told her he's still not sure. and furthermore (which i think was the most important thing) he said he doesn't he can support his girlfriend so much and that he wants his partner to be settled. that was what put her off, it could've seemed to her like their relationship might be difficult in the future.
a lot of people talks about being honest/dishonest in this context. for me it's true that Jinyoung is a honest person and he was open about his feelings and thought. but also we need to remember that he didn't really thought abot how his words can affect the other person. while being honest it's also important to being considerate about how it sounds. as the hosts said, their talk seemed to be more like a rejection than invitation.
to leave his topic, i'm very fond of Jongwoo. he was amazing, pursuing his feelings, while being considerative and caring. he tried not to put pressure over Seulki while also being open for her and supportive. that was what won her heart. because even if she didn't feel direct chemistry with him, she felt comfortable, secured and this is what is the best base for the further relationship. i think they might be a real couple in the future.
