Really strong 4. A better couple than the one on the first story. Seme is nice but teases uke to get what he wants, which he do get coz the uke gives it to him willingly, all except for a direct love confession. It's interesting that to the end, the uke was really not able to do that one thing, but was instead consistent in showing his affections through actions and roundabout statements, I like that though the seme was pushy with his "game" he trusted the uke enough to know that he will not cheat, and he did know when to call it off when the uke contacted him out of desperation, eventhough at that point his goal of making the uke say he likes him is still not attained.
As for the extras on the first couple, really that plot should've been on their main story, it would've been a good chase arc for the consistently cheating uke; coz at this point in the story, the uke is already repentant and is wholeheartedly devoted to the seme, so to pull off that kind of plot device, it just seems so out of the blue- all you feel is sadness and pity for the uke, and very little sympathy for the seme who just comes off as paranoid and possessive with a proven record of violent streak. It just doesn't look good for both.
